poor area of Los Angeles, California. Many of the students in the school had serious problems with illegal drugs, gangs and violence. The school was in danger of losing its official approval to operate.

    Mr. Escalante's students were mostly MexicanAmericans from a Spanishspeaking area of the city.

the group to work hard. He told them basic math was too easy and that they had the ability to do harder

work.

    The officials at the testing company suspected the students of cheating. Mr. Escalante protested(抗议). He said the students were being rejected because they were from a poor school. He urged his students to

take the test again.

     Twelve of the students repeated the test. And again, They all passed. Five earned top scores. Mr.

Escalante's students went on to become engineers, scientists and university professors.

     Jaime Escalante received many teaching awards. A movie about his success, Stand and Deliver, was
