Open Session-Based Online Courses

Our session-based Online Programs are rigorous, deadline-driven courses designed to enrich and accelerate academically advanced students in the areas where they show the strongest abilities. Tests (if any) are taken according to the course schedule, and the course choice depends on the student's previous education background—not necessarily on their age or grade.

New! Remote Testing Option
CTY now offers an online version of the School College and Ability Test (SCAT). Log into MyCTY or sign up for Talent Search to register today. Learn more.
