Proficiency Requirements Scenario H Suppose you’re teaching in a district that requires students to attain eighth-grade proficiency in mathematics in order to enroll in Algebra I in high school. Looking at students’ performance the preceding year, you found the results in Figure 8 for the Latino and African American students who make up your school’s entire student body.

• A score of 65% on the district math test is considered proficient, and • A school is considered “low performing” if less than 50% of students in any student

subgroup reach proficiency. Figure 8: 2005–06 Achievement in Grade 8 Mathematics
