Once a student has gained admission to Orlando Science School, they are not required to complete Online Applications or Lottery procedures for each following year. Existing students receive a Re-Enrollment form at the start of the calendar year on which they indicate whether or not they intend to return for the following school year.

Students who specify on their Re-Enrollment form that they intend to return will be saved a seat.

Students who elect not to return or do not submit their Re-Enrollment form by the specified deadline will lose their seat at the school. Students who withdraw from the school are required to reapply and go through the Lottery and Waitlist process to try and gain readmission.
