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
