During the 79th Texas Legislature, the bill "Advancement of College Readiness in Curriculum" was passed (THECB). As a response to this, high schools and colleges have combined forming an early college high school. The result of this union was a program that condensed the time it took to complete both the high school diploma and up to two years of college during the high school years, yet retaining its rigor. Early college high school replaces remediation with acceleration. In South Texas a lack of college readiness for low-income high school students has resulted in being unprepared for college and subsequently low college graduation rates. As a response to the THECB and the need for a higher graduation rate in college, the state of Texas implemented TSI readiness standards. This research study asked whether attending an early college high school prepared high school students to be college-ready. The purpose of this ex post facto study was to test whether Early College High School (ECHS) students were more prepared for college than the traditional high school students as measured by the Reading and Math End of Course (EOC) exams while controlling for grade 8 STAAR scores. No significant difference was found between the traditional and early college high school on Math. However, there was a significant difference between the traditional and early college high school on Reading and the type of school accounted for 44% of the variance in Reading. This is considered a large effect size.
