AstroChallenge is currently only open to Singaporean schools. It is tailored for students in Secondary Schools, Junior Colleges, Polytechnics, and similar Institutions. Schools are free to send in any number of teams per category:

● Senior Category

For all Junior Colleges, Polytechnics, and Institutes

● Junior Category

For all Secondary Schools Schools with Integrated Programme (IP) may also send their students in the Junior Category if they are in a year system equivalent to Secondary 4 or below, and are 16 years old and below as of 1 Jan of the year AstroChallenge is held.

The registration fee changes from year to year due to different operational costs and logistical requirements. For reference purposes, the registration cost was $70 per team of 4 to 5 members for AstroChallenge 2021, or $20 per person for teams of less than 4 members at the point of registration.

AstroChallenge is held annually in June. We try to avoid clashes with other competitions such as Olympiads, or national examinations such as the O Level Higher Mother Tongue Oral Examination.
