Check your Application Dashboard for missing materials and other application information.

For 2024, there will be two rounds of applications. The first round deadline is February 5th, and our second round deadline is March 11th. Students applying for financial aid must submit by March 11th, and any applications received after March 11th will only be considered on a rolling basis if program space allows.

Students who are currently in 10th and 11th grade (rising junior and senior while the program is in session) are eligible to apply.

Students who would like to participate in any of our programs must apply for admission; completed applications are submitted to the Admissions Committee for review.


Full Pay Applicants

All students applying for full pay admission to the Carleton Summer Liberal Arts Institute MUST submit: 

1. Your completed online application form.

  • Background information
  • Short essay answers (500 words or less)
  • Completed certification and review of your application

After you submit your application, you may submit the following materials through your Application Dashboard:

2. A copy of your most recent high school transcripts.

  • Your transcripts can be either official (mailed directly to us from your school counselor) or unofficial (uploaded to your online application dashboard or mailed to us from you).
  • Transcripts should begin with grade 9 (freshman year), include Fall 2023 term grades, and include a list of courses you are currently taking.
  • Transcripts must include the name of your school, course titles, and grades earned.
  • Please do not submit printouts or screenshots from online grade portals.

3. Two recommendation letters

  • As a part of your online application, you will be asked to provide contact information for two references. Once you have entered in their contact information and completed the recommendation section of the online application, your references will be emailed a link for submitting their recommendation letter.
  • Your references must be able to speak to your academic abilities. All recommendation letters submitted are reviewed by the admissions committee.
  • You can submit your online application before your recommenders submit their letters, but your application will not be considered complete without the recommendation letters. However, we allow recommenders to submit their letters up to one week after the deadline.
  • Your recommendations are your responsibility, so make sure to check in with your recommenders if the deadline is nearing and they have not yet submitted their letters. Some recommendation request forms get lost in junk or spam folders, so you should confirm your references received and completed the form. If the link expires, you can send an updated link once you have certified and submitted your online application.

4. $75 Application Fee

  • Each student will be required to submit a $75 application fee with their application. This covers the detailed processing and review time invested into our applications.
  • The application fee form will ask for the student’s Colleague ID number, which can be found on the student’s Application Dashboard after they submit the application.
  • Please allow 2 business days for the application fee requirement to appear marked as “received” on the student’s application dashboard.

5. Program-specific documents

  • This could include a writing sample or portfolio, and not all programs have specific document requirements. Check your application dashboard and program web page for more details.

6. Optional Items (NOT Required):

  • An unofficial copy of your PLAN/ACT and/or PSAT/SAT scores.
