The document outlines 4 stages of second language acquisition:
1) Silent or receptive phase where students focus on comprehension and may use gestures but not words.
2) Early production where students begin using 1-2 word phrases and expanding vocabulary but have limited conversation skills.
3) Speech emergence where expression includes phrases and grammar attempts and students can respond to basic questions.
4) Intermediate fluency where students can have conversations, understand grade level concepts with support, and make some errors but not interfere with meaning.
