Thank you for your interest in Triangle Math and Science Academy - TMSA Triangle! We held our public lottery for the 2023-2024 admission on February 16, 2023 and received more than 9,000 applications. Please note that late applications after the public lottery will be placed on the bottom of the waitlist.

Apply to TMSA for 2023-2024

TMSA Triangle is a tuition-free public charter school focusing on Science, Technology, Engineering, the Arts, and Math (STEAM) in Wake County, NC. We serve over 1,000 students from kindergarten through 12th grade. Our Cary campus serves K-8 and the Apex Campus serves high school students. Both campuses operate under TMSA Triangle.

We do not discriminate against students on the basis of sex, national origin, ethnicity, religion, disability, academic, artistic, athletic ability. We are an open enrollment school and admit any child who qualifies to attend a public school in North Carolina regardless of the school district the child resides in the state.


New families are required to submit an initial application due to the limited spots available in our schools. 

Please note that the initial application is for new students only. Current students at TMSA do not have to go through the initial enrollment proceedings. Current families wishing to re-enroll are given “Intent to Return Form” to complete and return to the school every year in the stated time frame.

We accept applications year-round. However, due to the high demand for our school, we recommend new families to apply to the school between December and mid-February for the upcoming school year.

If you have any further questions about our admissions process, please call (919) 388-0077 or send email to [email protected].


We are looking forward to welcoming you and your student to our information and tour night. Visiting our schools is a great way to get a true sense of the culture, curriculum, and student life at Triangle. Our passionate faculty and dedicated administration team help you explore the school firsthand before you make your final decision.


We receive hundreds of applications every year beyond the number of seats available at any grade level. We conduct a lottery in every February to fill the seats in a fair and equitable way. Our lottery is publicly undertaken and may be attended by any member of the public.

We randomly select names or numbers through PowerSchool registration software. Once all available seats are filled, a waitlist will be established by listing the students in the order drawn. Multiple birth siblings will enter the lottery as one name or number, parents only need to submit one application. If that name or number is selected, then all of the multiple birth siblings shall be admitted. Late applications after the scheduled lottery will be placed on the bottom of the waitlist.

Triangle Math and Science Academy gives enrollment priority to qualified applicants to fill the available seats ahead of applicants without priority status. The eligible applicants, in the order listed, are:

1) children of employees and governing board members (by law, these students cannot amount to more than 15% of the school’s total enrollment) and,
2) siblings of enrolled students (by law, siblings include half-siblings, step-siblings, and children residing in a family foster home).

The lottery results are emailed to the winning applicants.


Applicants who receive a seat at Triangle Math and Science Academy will need to complete the necessary forms to enroll within the given two-week period. If the applicant does not notify the school of its acceptance of admission on time, the applicant will be deemed to have declined admission, and the first child on the waitlist will be offered admission.

The following items are needed in order to complete the enrollment process. If applicants do not have some of these documents available immediately, such as EOG test results or kindergarten physical exam, they can be submitted at a later time, but you MUST communicate with the enrollment office.

  • Government-issued photo ID for parent/guardian,
  • Copy of student birth certificate,
  • NC proof of residency through the utility bill, mortgage/lease document, etc.
  • Immunization records,
  • Guardianship/custody papers, if applicable,
