Andrei, whose native language is Russian, gets all of his instruction in English except for one period a day. During that period he goes to another room and works with a teacher who helps him with pronunciation, grammar, vocabulary, and oral comprehension in English. The ELL program he is in is best described as:
◦ an immersion program.
◦ an ESL pullout program.
◦ a sheltered English program.
◦ a maintenance EL program.
