Faculty & Staff

Accelerated Schools employs carefully screened professionals in every area of administration and instruction. All teachers are certified or eligible for certification in the specific fields of their assignments, and all have a specialty that complements the background of their associates.

Many teachers hold advanced degrees in education, special education, psychology, sociology, mathematics, and reading. Each teacher must also complete extensive independent study courses in behavior and computer classroom management.

In addition to the teaching staff, head teachers and educational counselors with special training in behavior management analyze the education background and factors of psychological motivation affecting each student. They hold regular conferences with students and parents throughout the school year.

Because the faculty holds itself responsible for the student’s education, weekly staff-training and review sessions are held. This allows the entire staff the opportunity to contribute to an individual’s progress.
