Data were collected from 11,927 students across two school districts in New Jersey. The report details the correlation between ISIP scores and NJSLA-ELA scores, indicating strong associations. Using multinomial logistic regression, the study outlines the percentile ranks necessary for students to achieve various performance levels on the NJSLA-ELA. The report also discusses the methodology used for classification accuracy analyses, revealing that between 62% and 81% of students were correctly classified regarding their performance levels. The findings aim to inform educators about the predictability of ISIP assessments and their implications for personalized instruction.
