The academy is tuition-free for New Hampshire residents. However, the limited space available for new students makes a lottery system necessary. All applicants who are eligible for the lottery are drawn and this order is used to create the waiting list each year. The school is physically located in Nashua, but is a New Hampshire public school and all New Hampshire students are eligible to apply for enrollment. Nashua students are not given priority over students from any other New Hampshire towns.
