Correctional Education: Why it is Only "Promising"
John Lewis
Abstract
Althougii many correctional education studies have identified various treatment
programs as being effective for reducing recidivism, few, if any, of these studies appear
to be above reproach when assessing their methodological vigor. This paper highlights
the shortcomings in the cunent post-treatment quasi-experimental design primarily
used to evaluate the effectiveness of various correctional education and vocational
training programs. It is argued that this research design is inadequate to offer a true
assessment of the impact of conectional education, especially if the outcome variable is
recidivism, since numerous plausibie variables that could impact program
impiementation, deiivery, and retention, as well as post-release variabies are missing
from the model This survivai analysis model, which evaluates oniy macro-ievel
variables, often discounts aiternative factors which might have caused a CE effect to
have been dampened, thus in most of the studies, evidence that CE works to reduce
recidivism is ambiguous. Further, repiication of findings is virtuaily impossible using
macro-levei variabies since their associated micro-ievei variabies often are different for
each iocation, faciiity, dassroom, and instructor invoived with the sites being studied.
An argument is made to take a more holistic approach to evaluating the effects of
correctional education programming, an approach which must start with the research
funding agencies and a movement away from recidivism as the primary outcome
variable.
Introduction
Since the late 1700's, incarcerated learners have relied on correctional
education (CE) and vocational training programs to enhance their chances of
not recidivating after reiease from prison. Those invoived with pianning,
delivering, and evaiuating correctionai education aiso believe that correctionai
education appears 'promising" in reducing recidivism (MacKenzie, 2002). The
term 'promising" is used because muitiple studies about correctionai education
286
The Joumai of Correctional Education 57(4)»December 2006 Lewis Why Correctional Education is Only "Promising"
have indicated only a weak, negative causal relationship between correctional
education and recidivism, and many of the studies that have found significant
support for this relationship have been piagued by weak methodological vigor
(MacKenzie, 2002). Arguably, today, we are only marginaily closer to answering
the question 'Does correctionai education reduce recidivism?' than was Robert
iVlartinson (1974) when he asked 'What works?'
Martinson (1974) often is associated with being one of the first researchers
to question whether any treatment program, educationai or vocationai, could
reduce recidivism. The Martinson report (1974) concluded by posing two
possibilities that would explain the findings, which suggested CE had little or no
impact on recidivism rates. The first was that 'It may be simpiy that our
programs aren t good enough - that the education we provide to inmates is
stiii poor education' (p. 49). The second possibie conclusion was that 'education
at its best, or that psychotherapy at its best, cannot overcome, or even
appreciabiy reduce the powerful tendency for offenders to continue in criminai
behavior (p. 49). What often is missed in iVlartinson's research is the fact that
he questioned the vaiidity of the research and research modei(s) as being too
pooriy designed in most of the studies he evaluated to offer any empiricai
support for the research findings. He did not state that correctional education
could not or does not reduce recidivism, but that the studies were too poorly
designed to offer any credence to their findings, regardiess of whether
correctional education was supported or unsupported in reducing recidivism.
Thirty years iater, the same criticism about research designs and the associated
findings stiii appear relevant (Cecil, Drapkin, MacKenzie, & Hickman, 2000; Hull,
Forrester, Brown, Jobe, & McCuiien, 2000; MacKenzie, 2002; Wiison, Gaiiagher,
a MacKenzie, 2000).
Tlie Current Correctional Education Evaluation Model The current research model for most correctional education is a post-treatment
quasi-experimentai design, with one treatment and one controi group, where
the groups are reieased from prison and monitored for one to three years after
release to determine the recidivism rate for each group. This survivai analysis
modei, which evaluates oniy macro-ievei variabies, often discounts aiternative
factors which might have caused a CE effect to have been dampened (e.g. post-
release factors), thus in most of the studies, evidence that CE works to reduce
recidivism is ambiguous. Further, repiication of findings is virtuaiiy impossible
using macro-ievel variabies (recidivism, CE, vocational training, release date)
since their associated micro-level variabies (definition of recidivism, type of CE,
287
The Joumai of Correctional Education 57(4)«December 2006 Why Correctional Education is Oniy "Promising" Lewis
CE deiivery method, dassroom environment, instructor expertise and attitude,
teaching methods) often are different for each iocation, facility, classroom, and
instructor invoived with the sites being studied.
For the muititude of CE studies that have identified a significant negative
relationship between CE and recidivism, the methodology employed often
vioiates key assumptions pertaining to probability sampling, measurement of
treatment, and/or statisticai anaiysis. The lack of scientific merit in this
particular research modei makes various programs appear effective in some
instances, but upon cioser evaluation the effect was either: 1) insignificant, 2)
invaiid due to seiection bias or attrition, or 3) iost in a muititude of programs
that made it impossible to assess exactiy which program or combination of
programs caused the reduction in recidivism.
MacKenzie (2002) noted that of the thirteen identified studies she reviewed
invoiving aduit basic education, oniy five possessed the methodoiogicai vigor or
scientific merit that permitted inciusion In her review. In reviewing the findings
of these five studies, MacKenzie noted that oniy two offered positive significant
findings that CE reduced recidivism, and one suggested that CE increased
recidivism, with the other two offering mixed resuits. Further, one of the studies
that supported the significant positive effects of CE could not segregate
educationai and vocationai treatments within the treatment group, ieaving the
researchers unciear about which treatment or combination of treatments were
necessary to reduce recidivism.
Wilson et al., (2000) reviewed 53 evaluations of specific CE and treatment programs. Of these 53 CE and treatment research studies, only three used
random sampiing, and high attrition ieveis compromised one of those. The
remaining 50 research studies were ali quasi-experimentai designs, but only
four had the statisticai controi to rate them higher than a 2 on the Maryiand
Scientific Methodology Scaie. Thus, out of the 53 CE and treatment research
studies identified by Wilson et al., oniy six rated higher than a 2 on the
Maryland Scientific Methodoiogy Scale 'A full 89 percent of the studies were
judged to be of poor methodoiogicai quaiity' (Wiison et al., 2000, p. 361).
Cecil et al. (2000) evaluated the findings of studies completed in the 1980s and
1990s that had researched the effects of 12 ABE and 5 Life-Skiil programs in
their ability to reduce recidivism. This evaluation found that most of the
research singulariy only focused on the program being evaiuated and faiied to
control for other programs and treatments. Further, these studies failed to
control for selection bias and there were inadequate foiiow-up periods after
reiease. Finally, in the 12 avaiiabie ABE evaiuations, which employed statisticai
288
The Joumai of Correctional Education 57(4) • December 2006
Lewis Why Correctional Education is Oniy "Promising"
tests, there were no statistically significant differences observed between the
treatment and the control groups (Cecii et ai., 2000, p. 213).
The evaluation of the five iife-skiiis programs found that aithough four of
the five evaluations possessed a reasonable degree of scientific merit (MSMS
scores of 3 or 4), the evaluations faiied to identify a statistically significant
difference between the treatment and controi groups. Aiso, on certain measures
of recidivism, the treatment group had a higher (but insignificant) rate of
recidivism than the control group.
Overaii, the assessment of the evaiuation iiterature of adult basic
education and life skills programs yieids incondusive resuits... Whiie these
studies assessed generally report positive findings, the iack of significance
tests, relatively few well-designed studies, and the existence of confiicting
data leads us to conclude that, at this point, there is not enough evidence
to draw definitive conclusions regarding the overall effectiveness of either
of these programs (Cecii et ai., 2000, p. 215).
Huil et al. (2000) found positive support for CE. 'These findings suggest that
successful completion of an educational program may be positively and directiy
reiated to post-reiease community adjustment' (p. 260). However, the
researchers acknowledged three research limitations: 1) the study did not
include information about attendance in other prison programs; 2) the study
failed to identify the motivational factors that caused individuais to complete or
withdraw from CE programs; and 3) the study faiied to identify the seiection
process for attendance in educational programs and prior education levels. The
inabiiity to address these limitations resulted in no statisticai analysis being
conducted to measure the effects of CE while controlling for other relevant
variabies. As Linton (2005) noted 'If the evaluator cannot pin down what
program is being evaiuated, what possible significance couid there be in any
numerical findings?' (p. 95).
The OCE/CEA three state recidivism study (Steurer, Smith, & Tracy, 2001) is
undoubtedly one of the most comprehensive studies ever compieted in the fieid
of CE and is possibly the most vigorous study that can be obtained using the
standard CE research evaiuation modei. Aithough the study conciudes that CE
can reduce recidivism (Grasmick, 2001; Wiikinson, 2001), the study suffers from
a majority of the shortcoming identified by Hull (2000) in his study. Treatments
could not be segregated and treatment lengths could not be determined, nor
could treatment during previous incarcerations be determined. How each
289

faciiity, throughout the three states, seiected who received treatment (most
serious offenders or best possibility of success upon release) could not be
identified, the treatment and controi groups were signlficantiy different on
variabies correiated with recidivism (age, race, arrest offense, etc.), and aithough
the direction of their reiationships to recidivism were identified, no statisticai
anaiysis was conducted to determine their standardized slope values or the
effects of CE while controiiing for other reievant variables.
Why CE Studies Faii to Repiicate Findings
Recidivism
Researchers must determine what wiii be used as a dependent variable(s) to
measure the effectiveness of CE programs. Recidivism is the most widely
accepted dependent variabie, since it is a primary outcome measure
acknowledged, or even mandated, by federal and state research funding
agencies (Linton, 2005), but this acceptance is not without criticism. Gehring
(2000) addresses the issue of using recidivism as a dependent variabie and
deveioped a matrix (p. 199) listing nine probiems with recidivism as a program
evaiuation measure. Joan Petersiiia aiso addressed this issue in the 1996
Encydopedia of American Prisons (McShane & Williams, 1996, p. 382). She noted
that recidivism is difficuit to measure because there is no agreement within the
criminal justice community about a definition. On the other hand,
conceptualizing or defining recidivism in different ways (re-arrest, reconviction,
re-incarceration, new offenses only, technicai vioiations, etc.) results in a
situation in which the data and results from one study often cannot be
compared to another, aithough both are measuring some form of recidivism.
Researchers most often define recidivism as re-arrest, reconviction, and/or re-
incarceration. Additional problems arise, however, as researchers attempt to
determine whether only new arrests shouid be the outcome measure, or should
re-arrest, reconviction, and/or re-incarceration inciude technicai parole
violations. By measuring recidivism at the macro level, micro causes for
recidivism are discounted (e.g., race, number of prior arrests, age at first arrest,
attitude and efficiency of parole officers, poiice officer discretion, social and
famiiy support factors). These discounted factors often are stronger indicators of
recidivism than attendance or compietion of CE (e.g., Langan & Levin, 2002;
Sabol, Adams, Parthasarathy, & Yuan, 2000).
A similar problem occurs when independent variabies used to determine
the cause for recidivism are measured at only the macro level. Researchers who
attempt to unravel the effects of CE on recidivism are confounded with multiple
290
The Joumai of Correctionai Education 57(4) • December 2006 Lewis Why Correctional Education is Oniy "Promising"
program treatments, poor institutional record keeping, and conflicting
definitions about what constitutes 'program compietion.' In reviewing the
iiterature about CE research, these differences often are ignored, affecting the
validity of the research (MacKenzie, 2002; Martinson, 1974; Wiison et al., 2000).
Assessing instructionai Deiivery MeOxods
Simiiar to the paroie officer's differentiai zeaiousness to enforce technical
violations that result in recidivism, educationai and treatment program
effectiveness are influenced both by the qualities brought to the classroom by
the correctional educator and by the instructional design. Measuring CE at the
macro level is to concur with the assumption that all correctionai education and
vocationai training are delivered effectiveiy and efficientiy in each ciassroom in
every correctionai faciiity, to the standard set forth by some reguiating agency.
Currentiy, aithough there are nationai standards for the preparation of
correctionai educators (see: http://www.ceanational.org/) adherence to these
standards is not mandatory; thus, states vary in their requirements for
correctionai educators. Many states find it less expensive to hire individuais
with minimai or no educational training to teach adult inmates, instead of
paying for state certified teachers. Even if state certified teachers are hired for
correctional education settings, they often are ill prepared to instruct in a
correctional environment.
Truthfuily, there is much about correctionai teaching for which we are
unprepared. The institutionai environment itself makes a great deai of
what we iearned for pubiic schooi teaching impossible... We feel alienated
and pooriy prepared for teaching in this most repressive environment. It is
no wonder that so many correctional teachers faii; either by ieaving
correctionai education or by accepting that education is just a
management strategy for the prison (Eggieston, 1992, p. 7).
Educationai Theory
Another factor that influences how the incarcerated iearner is impacted by the
treatment is how the materiai is presented. Simiiar to criminoiogicai theories for
reducing crime, the field of education has theories describing how people learn.
The style used by a particuiar educator is some admixture of personal
attributes, epistemoiogy, and theoretical perspective, which often is influenced
by the subject they teach. A major educational theory in CE is the learning
styles theory (Jurich, Casper, & Huli, 2001; Muse, 2001). Learning styles theory
291
The Joumai of Correctional Education 57(4) • December 2006 Why Correctionai Education is Oniy "Promising" Lewis
suggests that individuais perceive and process information differently based on
heredity, upbringing, and current environmentai demands.
Educators in the naturai sciences emphasize constructivism theory, where
meaning requires understanding the 'whoie" process instead of just memorizing
the parts. Other educational theories include behaviorism, observationai
learning, Piaget, neuroscience, brain-based learning, human inteiiigence, right
brain v. ieft brain, communities of practice, controi theory, and social cognition
(Biehier & Snowman, 1993; Eurich, 1990).
Learning wiii not occur if the correctionai educator faiis to Identify how
incarcerated learners grasp and retain materiai (e.g., Biehier 8 Snowman, 1993;
McKeachie, 2002). Any program wiii appear ineffective regardless of its true
effectiveness, if the materiai is deiivered in a manner, which does not foster
learning and retention. We again are confronted with Martinson's observation:
'It may be simpiy that our programs aren't good enough - that the education
we provide to inmates is still poor education' (p. 49).
The iVIedicai Modei Approach
The inabiiity to assess these variables, along with the probiems of
operationalizing and measuring recidivism, ensuring programs are implemented
and delivered as designed, the ethical and security concerns surrounding
random treatment and controi group assignment, treatment diffusion within the
confined prison environment, and a host of post reiease factors, suggest that it
is time to discard the traditional CE research model.
in evaiuating the effectiveness of correctionai and vocational education,
recidivism measures oniy one possibie outcome, often the return to a
correctional facility. It is argued that instead of using this survival anaiysis
modei, between treatment and non-treatment groups (which often cannot be
separated), that researchers should move to a more holistic approach. Even if
recidivism rates, as currentiy measured, do not espouse correctionai and
vocational education programs, this does not negate their other possible,
positive effects.
A more hoiistic approach, based initially on smaiier sampies and a
qualitative, medicai modei would permit a sociai productivity assessment of the
effectives of various CE and post-reiease programs. The outcome measures
wouid focus more on how various CE and post-reiease programs affected
reieased offenders, their famiiies, and their communities, whiie stiii controiiing
for recidivism and pubiic safety, without using them as the primary measures of
program effectiveness (e.g., Giever, Wiison, Zimmerman, Lewis, Staples, 2004).
292
The Joumai of Correctionai Education 57(4)»December 2006 Lewis Why Correctionai Education Is Only "Promising"
Ciever et al. (2004) recommended that future research about the effectiveness
of correctional and vocationai education shouid include individuai and sociai
indicators, as weii as recidivism, as measures of program success. Research
shouid focus on how correctionai and vocationai education impacts not only
on the former inmate, but also on community and family structure, child
development, and community safety. These measures of effectiveness should
include, but should not be limited to, how correctionai and vocational
education affects empioyment, family relations, income generated within the
community, positive decision-making, and intergenerationai mentoring.
Little research has been conducted to specifically identify what the
qualities-of-life are for those former inmates who have not returned to
correctionai facilities. From a more Masiowian perspective, what impact, if any,
has correctional and vocational education had on individual needs, such as
physiological, safety, sociai, esteem and self-actualization. Masiow (1972) noted
that the humanistic goal of education should be 'helping the person to become
the best that he is able to become' (p.163). He further noted that although this
often is not the goal of associative learning, such as that found in correctionai
and vocationai education programs, the experiences of participating in
education aiso offers humanistic experiences and interaction, thus offering seif-
deveiopment and seif-fulfiiiment opportunities.
Maslow's basic hierarchical needs include physiologicai (hunger, thirst,
sheiter) and safety needs (security and protection from physical harm). Future
research may question whether correctionai and vocational education offers a
former inmate a better chance at obtaining these basic needs. In addressing
sociai needs, research shouid attempt to address if correctional or vocationai
education had any impact on famiiy and community acceptance, on family
cohesion and affection, and on future and past relations and friendships. What,
if any, were the effects of correctionai and vocationai education on the
individuai? Did these programs aid the individual in achieving goals, obtaining
positive status in the community, in obtaining recognition and attention from
those s/he respects the most (esteem). Finaiiy research shouid determine if there
is a link between correctionai and vocational education and self actualization.
Limited research, mostiy from the quaiitative paradigm has started to address
these issues, but not from a correctionai or vocational perspective (e.g., O'Brien,
2001; Clear etai., 2001).
In discussing educational needs, Richie (2001) notes:
Most women report not having the academic or job-related skiiis or
293
The Joumai of Correctionai Education 57(4) • December 2006
Why Correctionai Education is Only "Promising" Lewis
experience to support themselves once they are released. They frequently
depend on famiiy members who themselves have limited resources, pubiic
agencies that have rigid eiigibiiity requirements for their services, and/or
episodic support from community-based agencies such as food pantries.
The women I interviewed described how the puii toward iiiegai activity
becomes more stronger as they exhaust these options (p. 377).
The need for empioyment and other physioiogicai and safety needs (subsistence
and safe, secure, and affordabie housing) were closely related or inten-eiated to
educationai opportunities (Richie, 2001). Ciear et ai. (2001) remark: Training and
education are the foundation of quality empioyment' (p. 346).
From a community perspective returning former inmates can be both a blessing and a curse, if former inmates return to oid habits they add disorder to what often is an already disrupted community. If the former offenders possess the skiiis, knowiedge, and attitude to successful and legaiiy reintegrate into the community, they offer an improvement in the community's quality-of-iife. Their successful presence can move community members, especially chiidren, from a ioss of seif-worth and seif-esteem, to becoming successful community members, thus enhancing society as a whoie (Clear et al., 2001, p. 343 - 346).
Conciusion
As with aii research studies, inciuding those designed to evaiuate CE, the
conceptual model must be correctly specified. Accurately specifying the model
requires the researcher to ensure that the modei contains aii the reievant variabies,
including those reiated to the experience, qualifications, and delivery methods of
the correctional educator. The instmctional method and teacher's
experience/attitude also are plausible factors that affect student comprehension
and retention, as weii as attrition rates, which are key issues when attempting to
assess the tme impact of CE. The research model cun-ently used to evaluate most
CE programming is limited to macro variabie assessment, which enhances the
plausibie threats of intemai, statistical conclusion, construct, and extemai validity.
A new research model is suggested that wouid offer a broader perspective
about the piausibie effects of CE programs. To transition to this more holistic
model, support would be needed from not only the researchers who assess the
effectiveness of CE programs, but from the funding agencies, who need to
reaiize that the current CE evaiuation model they favor, with its restrictions and
shortcomings, is an inappropriate modei to assess the true effects of CE
programs. Since Martinson's assessments of the modei in the 1970, through
294
The Joumai of Correctional Education 57(4)»December 2006 Lewis Why Correctional Education is Only "Promising"
one of the most comprehensive CE studies conducted to date (Three State
Recidivism Study), the modei has proven to be ineffective in accurateiy
evaiuating the impact of correctional education and vocational training
programs. Linton (2005) is absolutely correct in his statement that 'If the
evaluator cannot pin down what program is being evaiuated, what possible
significance couid there be in any numericai findings?' (p. 95) and the argument
made here is that the traditionai model for evaluating correctionai education,
with its dependency on macro-level and misconceptuaiized variables, does not
reflect the true impact of correctionai education on the individual, his/her
family, or the community.
