John Q. Easton 2007¶

John Q. Easton, Stuart Luppescu, Todd Rosenkranz. (2007). 2006 ISAT Reading and Math Scores in Chicago and the Rest of the State.

q2 · i2 · associational · r2

Observational analysis of 2006 ISAT math scale scores comparing CPS to the rest of Illinois across grades 3-8; the printed standardized effect sizes are d = 0.72, d = 0.60, and d = 0.52 for grades three, six, and eight.

"There is a 21 point difference between Chicago students and students in the rest of the state in grade three (0.72 SDs), an 16 point difference in grade six (0.60 SDs), and a 15 point difference in grade eight (0.52 SDs)."

Discussion¶

Related Claims¶

• The gap between Chicago Public Schools students and other Illinois students in ISAT reading is about half as large in eighth grade as in third grade — related
• When compared within racial/ethnic groups, large CPS-versus-rest-of-state gaps disappear, and some CPS groups outperform their counterparts — related
• ISAT cut scores differ by grade and subject, with eighth-grade mathematics requiring a high score and eighth-grade reading a relatively low one to meet standards — related
