Analysis of 42,456 matched CPS students' EXPLORE and ACT scores across 2005-2007 junior cohorts shows the score-to-probability curve is "very steep in the middle," rising from under 1 percent at low scores to 55 percent at 17 and higher thereafter.

"An EXPLORE score of 17 is the "tipping point," where students have greater than a 50 percent chance of reaching 20 on the ACT. Virtually all students with high EXPLORE scores (18 and above) make it to 20 on the ACT."

Related Claims¶

• Combined strong academic culture and high grades more than double EXPLORE-to-ACT gains at every starting score, including moving students from an EXPLORE of 17 to an average ACT of 20.7 — related
• CPS students make smaller improvements on sequential EPAS tests from grade to grade than students nationally with the same prior scores — related
• Logistic regression can identify the ELP score at which students have a probability of 0.5 of being proficient on the academic content assessment, as a candidate English-proficient standard — related
• Students who fail to reach an ACT 20 gained only 0.6 points from PLAN to ACT versus 3.3 for those who reached 20, falling behind expected gains — related
