Application Process & Deadlines

Applications are submitted using MyCTD, the online course application system. Applicants are encouraged to apply early; many courses begin to fill as soon as mid-March. Complete applications are reviewed as they are received starting January 2. Applications are reviewed in the order in which they are completed.  Incomplete applications do not "hold a spot" in the desired course.  Additionally, the $500 deposit does not hold a seat in a course.  Once you have paid the deposit and submitted the appication you will recieve an email with further instructions. You will then be able to return to the application and select View Application Details to upload any necessary documents and to get the teacher recommendation link if necessary.

The grades 4 to 6 Solstice Summer Program welcomes applications from returning applicants as well as new scores and portfolio applicants. Before beginning the online application, determine which type of applicant you are based on the descriptions below.

Returning Applicant
You are a returning applicant if you are in grade 4 through grade 6 and you meet both of the following criteria: 

  • You have successfully completed a CTD course through the Weekend Enrichment Program, Summer Program or Online Program at the Emerald Tier, or a tier with a higher score requirement, within the previous twenty-four months. 
  • You are now applying for a grades 4 to 6 Solstice Summer Program course with the same qualifying subject area (Verbal or Math) as a CTD course you previously completed.

New Scores Applicant
You are a new scores applicant if you are in grade 4 through grade 6 and you meet one of the following criteria:

  • You have not attended any CTD program for the past two years and you have qualifying grade-level test scores (Verbal or Math) for your desired course that are no more than two years old.
  • You have previously attended a course with the Weekend Enrichment Program, Summer Program, or Online Program, but you are now applying for a course with a different qualifying subject area (Verbal or Math) and you have qualifying grade-level test scores. 
  • You have participated in above grade-level testing such as the PSAT™8/9 test taken in grades 3 through 6 (NUMATS).

New Portfolio Applicant
You are a portfolio applicant if you are in grade 4 through grade 6 and the following is applicable to you:

  • You do not have qualifying test scores because you have either:

             1) never taken a nationally normed standardized achievement test 


             2) taken this type of test but not achieved a qualifying score.

 An Admission Portfolio includes the following documents:

  • Required: one teacher recommendation form indicating that the student is performing 1½ to 2 years above grade level in the subject area of the course to which the student is applying.
  • Required: most recent school report card indicating exceptional performance in the subject area of the Solstice course to which the student is applying.
  • If available: most recent state testing report (e.g. NWEA/MAP); or any results of a grade-level test.

Please note that students are to apply to the grade level that they are in as of January 2nd for Summer Program courses.  For the purposes of the Summer Program, students are considered to be in the grade they just completed and NOT the grade they will enter in the fall.

Applicants are encouraged to apply early, as many courses close by mid-March. Due to the rolling enrollment nature of our program, courses that are listed as available may close before a student's application is complete and comes up for review.  We strongly suggest listing second and third choice courses on applications. Applications are processed and reviewed by Admissions staff when all necessary documentation has been provided through the applicant's MyCTD account. 

It can take up to a week for our staff to first review newly submitted applications as well as any documentation provided to complete an application later. Until our staff has verified the documents it will not yet be reflected in what you see in MyCTD.  We kindly ask you to not call nor email our office to confirm receipt of documentation or application items within a week of submitting them.

It may take 2 to 4 weeks for an admissions decision to be made once the application is complete.  You will recieve an email once an admissions decision has been made.

High academic standards and a diverse student body ensure that CTD students learn not only from their teachers but from one another. Students come from around the world, and share a common love of learning.

Solstice students enroll in one class per two-week session. Classes meet for five and a half hours per day. In order to maximize personal attention, Solstice courses are generally limited to 18 students per class. Each class has a master teacher and a teaching assistant, who work together to get to engage students in hands-on activities and challenging lessons. Solstice courses are intended to build upon a student's strengths; courses do not remediate areas of weakness. Each course is an intensive experience, and approximately one hour of homework is assigned each night. Solstice students living on campus attend mandatory study sessions led by teaching assistants on Tuesday and Thursday evenings. Students who commute to campus daily are encouraged to participate in these study sessions, as well as in afternoon activities.

Students receive a final evaluation on achievement and performance in the course; areas in need of further development; and student work habits and attitudes. Solstice courses are generally limited to 18 students.

Campus Life & Daily Schedule

Solstice students develop life-long friendships and enjoy a summer on Chicago's North Shore under the supervision of professional, caring staff.

Residential Students
Residential students are assigned to co-gender floors, but are roomed by gender. Accessible bathrooms are available on each floor. Students eat with staff and University community members in dining halls.

Intersession stays are available for residential students attending consecutive sessions for an additional $175 fee.

RESIDENCE HALL AVAILABILITY: Northwestern University residence halls are undergoing a major renovation project for the next several years. While CTD strives to provide space for all students who wish to reside with us on campus, available rooms may be limited and will be provided on a first-come, first-served basis. Due to renovation schedules, residence halls assigned to CTD may not have air conditioning.

Commuter Students
Solstice students who prefer to reside at home while participating in the Summer Program may choose to commute. Commuter students are dropped off and picked up at a central location monitored by Summer Program staff, and are encouraged to participate in afternoon activities and evening study sessions.

Safety & Conduct

CTD takes every reasonable step to ensure student safety. Faculty and staff provide clear conduct guidelines and careful supervision. Students are coached in safety procedures, including the use of on-campus emergency phones; student ID cards are worn at all times and include emergency phone numbers on the back.

Summer Program participants must adhere to the CTD Honor Code, which establishes standards and expectations for student behavior and reflects CTD’s commitment to fostering character development, integrity and respect. Summer Program rules and policies help ensure the safety of our students and staff, and students are expected to abide by them.


Residential students in Solstice are encouraged to bring personal laptops or tablets with them to assist with coursework. Some Solstice courses require students to bring a computer; check course descriptions for details.

International Students

TOEFL, TOEFL Jr., or IELTS scores are required of students for whom English is not the first language.
