Application Process

Please note: Beginning for summer 2022, students are to apply to programs and select courses based on the grade they will enter in fall of 2022.

The CTD Encounters Program welcomes applications from any interested student. CTD Encounters courses are part of our Amber Tier, open-enrollment programs.  There is no need to provide further documentation once you submit your application.  Please do ensure that you are registering for the correct grade.  For summer 2022, please register according to the grade your student will be in as of fall 2022. You can access the application online at

Application Deadline

Applications must be complete one-week prior to the start of the class. Applications completed after the deadline may be reviewed on a case-by-case basis.


CTD Encounters at Home courses are at the Amber Tier for eligibility, which is open enrollment. There are no test scores or further documentation required for participation. Please note that successful completion of a CTD Encounters at Home course does not pre-qualify students to enroll in future classes outside of the Amber Tier.

Requests for Grade Advancement/Acceleration

CTD course content is advanced or grade-level accelerated, as reflected in course descriptions and the standard admission requirements. Though course content is advanced, students can engage with intellectual peers who are also age- or grade-level peers. Therefore, most students should apply for courses aligned to the grade-level in which they are currently enrolled. Still, for some students demonstrating a need for an even higher level of instruction than CTD’s advanced and accelerated courses already provide, further acceleration may be an option. Visit the Requesting an Accelerated Placement web page for more information about the process, timeline, and required materials.

Course Details and Supplies

Students engage directly with their instructor and classmates through an online video conferencing platform (Zoom) for the duration of the course.

CTD Encounters at Home runs for 3.5 hours on a single weekend day during the school year, and full-week 3 hour sessions in the summer. Course materials will be made available to families prior to the start of the course.


Some courses may have required or recommended supplies that families will be responsible for obtaining prior to the course. Supply lists and recommended suppliers will be provided to parents at least 10 days prior to the course in which they are needed. No course will have supplies that exceed $30 (before shipping and handling), and many required supplies will be common household items that may already be in the student's home.

Students are required to have a laptop or tablet with a camera, a microphone, speakers and/or audio jack, the ability to type/keyboard, and the ability to connect to the Internet. Students need access to a stable internet connection and an updated web browser. 

Zoom is the conferencing software that will be used for the live course sessions. We recommend watching the Zoom for Students tutorial video prior to the start of class.

Program Orientation

Student acceptance emails will contain a link to a Family Information webpage that includes program information and the Student and Family Handbook.

Instructors will help students navigate the features that will be utilized within Zoom at the start of the class. CTD still recommends, however, that students watch the Zoom for Students tutorial video prior to the start of class.

Primary communication with the course instructor and/or classmates occurs within Zoom.
