In 1974, Mr. Escalante was hired at Garfield High School to teach math. The school was in a poor area of Los Angeles, California. Many of the students had serious problems with illegal drugs, gangs and violence. Many of Mr. Escalante’s students were the worst students at the school and were thought to be "unteachable."

He told his students that he believed in them, but they must have the desire to be successful. Jaime Escalante started an advanced math program with a small group of students. Advanced Placement is a program of college-level classes and tests. In 1982, 18 of his students took the Advanced Placement test in calculus and they all passed. Mr. Escalante’s students went on to become engineers, scientists and university professors. The advanced math program at Garfield became extremely successful over the next several years. Jaime Escalante received many teaching awards including the Presidential Medal of Excellence in Education.
