AYP Consequences and Erasure Behavior

Vincent Primoli Data Recognition Corporation

AYP Classifications• Made AYP (Made) –met all AYP criteria

• Level 1 (L1) –did not meet criteria for first time

• Level 2 (L2) – did not meet >= two years. Internal changes enacted to address problems.

• Level 3 (L3) –did not meet >= four years. External sources of assistance may be enacted.

• Making Progress (MP) –met AYP criteria for first year of two-year probationary period

Data

• Erasure– SGS rates by erasure type (WR, RW, WW) and test type (OP, FT) – SGS outlier scores by erasure type and test type

• AYP– School-level AYP classifications for previous eight years

• Performance– SGS Z-scores – performance relative to grade-subject mean

• Demographic– School-level percent students eligible for free\reduced lunch

Conclusions

• Increased likelihood of aberrant rates in probationary schools

• More failure, more disproportionate• More failure, stronger correlation

– Erasure proficiency and performance– Erasure proficiency and erasure rate likelihood

• Directional AYP differences
