Subclaims¶

q2 i? The study established a threshold of 6 on a 1–10 index of Emerging Academic Competencies and Learning Engagement Competencies, and the percentage of students above the threshold matched the cohort's actual 37 percent proficiency rate. → Jessica F. Harding 2019

q2 · i? · associational · r2

Threshold-setting analysis on the same 3,521-student administrative dataset. The article states "The percentage of students above this threshold matched the actual 37 percent proficiency rate of the study cohort in grade 3." Accuracy is at the cohort level, not the individual level.

"The study established the threshold of 6 on a 1-10 index of the two KEI dimensions to predict whether students would be proficient. The percentage of students above this threshold matched the actual 37 percent proficiency rate of the study cohort in grade 3."

Discussion¶

Related Claims¶

• Kindergarten entry scores predict grade 3 reading proficiency: Philadelphia kindergarteners with higher KEI scores in 2014/15 had higher grade 3 PSSA ELA scores — a broader claim this one bears on
• The KEI threshold was accurate for the cohort despite large individual-level prediction errors (53% of proficient and 73% of non-proficient students correctly classified) — possibly the same claim (merge candidate)
