psychological Assessment

The Peckham Decision dictates that school psychologists in California may not use intelligence testing on African-American children to determine special-education placement. This is due to a cultural bias because a large percentage of African-Americans were being placed in the Educable Mentally Retarded category. 

How might this decision help and potentially harm African-American students with special educational needs? Remember to support your arguments with information drawn from the online content, the textbook, and other credible, scholarly sources to substantiate the points you are making.  Apply APA standards to writing and citations to your work.
