Subgroups 1 List of subgroups that are consistently and significantly higher w/ TLs 1 chart w/ effect sizes for significant subgroups 2 charts w/ proficiencies and scale scores for significant groups –NCOSP TLs represented as colored bars –Non-TLs represented as yellow bars

Subgroups Subgroups with significantly higher Sci. scale scores that have consistent (or near consistent) results across 5 th, 8 th, 10 th –free-reduced lunch (5-8-10) –Hispanic ethnic group (5-8-10) –Special Education (5-8-10) –Level 1 and Level 2 for same year Math (5-10) –Level 1 and Level 2 on 8 th grade sci. WASL (10 –only grade applicable) – not found on 5 th to 8 th grouping

Subgroups Scoring Significantly Higher with NCOSP TLs Effect Sizes (Larger #s = greater separation between TLs and Non-TLs) SubgroupElementary (5 th )Middle (8 th )High (10 th ) Hispanic Free-reduced Lunch Special Education Math Level 1.18 Not significant.11 Math Level 2.23 Not significant.08 Science Level 1Not available Not significant.24 Science Level 2Not available Not significant.17
