Four payment quarters
Families may use four quarterly instalments even though Sigma remains academically a three-term school. Quarterly billing is a payment convenience, not a fourth academic term.
Summer 2027 launch
Summer Session 1 runs July 5-29, 2027, followed by the Back-to-School Academy from August 2-19. Screening, placement and orientation follow before Full School begins on September 6.
