AlphaStar Academy mainly considers teaching, competition, and education background as well as passion and dedication for the subject when hiring full-time and part-time teachers.
We hire our instructors and TAs from a pool of High School, College, Ph.D. students, school teachers, and University Professors. Our faculty have teaching/coaching/tutoring experience and have expertise in the subject area, regardless of their age.
They have participation and/or training experience in national/international math competitions and Olympiads in Math, CS, and Physics such as USAMO, USACO, USAPhO, IMO, IOI, and IPhO.
They are role models and inspiration for students with their backgrounds and achievements.
