              Collin AEL General Information

Developmental Education (DE) courses are designed to provide students with basic skills to achieve success in college-level courses and to pass the TSI (Texas Success Initiative) tests. 

DE includes courses in English as a Second Language, Developmental Mathematics and Integrated Reading/Writing courses. The instructional formats of DE courses vary and include computer-based, lecture, online, express, weekend, self-paced, and non-course based formats.

*Collin College has implemented Co-requisite DE Courses - a course format which allows you to enroll in credit Math, English and other credit courses immediately, when you also enroll in a developmental support course.
