q2 i? Underlying eighth-grade achievement among students included in test reporting was more than one-half standard deviation higher in the 1998 cohort than in prepolicy cohorts. → Allensworth 2004

Evidence¶

Allensworth 2004¶

Allensworth, E. (2004). Ending Social Promotion: Dropout Rates in Chicago after Implementation of the Eighth-Grade Promotion Gate. Consortium on Chicago School Research. https://consortium.uchicago.edu/publications/ending-social-promotion-dropout-rates-chicago-after-implementation-eighth-grade

q2 · i? · causal · r2

Cohort averages of underlying achievement from hierarchical linear models of ITBS score growth, plotted in Figure 3. The report states achievement was more than one-half of a standard deviation higher than in prepolicy cohorts, among included students.

"the test score of an included student who was at the 50th percentile in the 1998 cohort would have been at the 70th percentile in the 1992 cohort."

Discussion¶

Related Claims¶

• Eighth-grade retention rates surged from under 2 percent prepolicy to 8.3 percent in the first policy year, peaking at 11.1 percent
• The eighth-grade promotion gate had the largest impact on ninth-grade enrollment, with almost 2,900 fewer students advancing in fall 1998
• Retained students struggled in their second time through the promotional policy, with only about half meeting cutoffs and eighth graders doing worst
• Average TAP scores rose substantially for students who enrolled in ninth grade, but the 1997 high school redesign appears to have had only a modest impact on skill development — related
