Stratford High School consists of four houses, Amess (red), McAllister (yellow), Trimble (green) and Tyrer (blue).

Although being considered a small school, Stratford High participates in many extra-curricular programs, including a school production, participation in the Smokefree Stage Challenge, many sports teams, cross-country, athletics and swimming sports events, and many art and culture events.

Stratford High School has a prominently strong Kapa Haka group that are involved in local competitions in the region.

Having introduced the school haka in 2011, it is used in welcoming and sporting events.

Students are involved in a wide range of musical activities such as the Variety concert and the annual Stratford Lion's Awards.
