It is classified as a National Vocational School under the School Education Law.

Background
The school building was originally a metropolitan high school that had been abandoned due to unification and reorganization a year before the events of the Fairy Dance arc and was awaiting demolition. Hisashi manages to take ownership of the School Building and received Legal permission to rebuild the School specialized in teaching the middle and high school students that had returned from SAO and had fallen behind in their studies due to being in a comatose state for two years and student who education was poor or suffering from a mental health issue or stress and those who haven't attend school for a long time. Unlike most schools in Japan, the SEERS school does not have entrance exams nor school fees and all students who attend the school are eligible to take the entrance examinations for university after graduating. Such extremely good treatment had received criticism for a while.

Curriculum
The teaching staff at the school mostly consists of re-employed teachers, who had retired from old age but volunteered to serve part-time or people who worked at FEAST. All the teachers candidly faced their students, thus there was no need for students to intentionally hide their past.

An EL panel is used instead of a regular blackboard and students write on a tablet PC, instead of using notebooks while homework to the students is sent over wireless LAN.

Uniform
All students at this school have to wear a blue, blazer-type uniform. The male version of the uniform consists of a dark blue jacket with the school's insignia on the left side, a white, long-sleeve shirt with a collar that has two light blue lines forming an X on each side and the same insignia of the school on its left side as the jacket, a red tie, and dark blue trousers. The female version of the uniform differs from the male version in that females wear a dark blue skirt with knee-length or longer socks instead of trousers, a red ribbon instead of a tie and wear a cropped version of the jacket.[7] During summer, the students usually go to school without their jackets and wear short-sleeve version shirts.
