q2 · i? · associational · r2

Correlational analysis of K-2 assessment records from Chicago Public Schools (2013-14 to 2021-22) using descriptive statistics and correlations. The authors report that "All of the assessments are positively correlated with each other, surpassing the 0.50 threshold."

"All of the assessments are positively correlated with each other, surpassing the 0.50 threshold of a moderate relationship, and many are highly correlated, surpassing a 0.70 threshold of a strong relationship."

q2 · i? · associational · r2

Same correlational analysis of Chicago K-2 records. MAP showed the strongest correlations, "ranging from 0.78 to 0.83" with ACCESS, DIBELS, and TRC-English, and 0.65 with TRC-Spanish.

"The MAP shows the strongest correlations with the other assessments, ranging from 0.78 to 0.83 with each of the other assessments (ACCESS, DIBELS, and TRC-English), except TRC-Spanish, where the correlation is 0.65."

Related Claims¶

• K-2 assessment and latent scores predict third grade ELA grades with correlations from 0.52 to 0.63 in pre-pandemic cohorts — related
• Post-pandemic, K-2 scores predict third grade ELA outcomes with smaller but still moderate-to-large correlations (0.30-0.64 for grades; 0.47-0.81 for IAR) — related
• TRC-Spanish is the assessment least correlated with the others, though strongly correlated with TRC-English — related
