NBPTS EMC Literacy Standard 7: Writing Practice Test

Subtractive bilingualism describes how a second language is learned in relation to a first language, particularly how the first language is affected as the second is acquired. In this item, the statement that the second language is learned after the first has been established and does not affect the first captures a sequential introduction where the first language remains intact. This framing emphasizes that L2 is added later without displacing L1, which aligns with how subtractive bilingualism is depicted in some instructional contexts.

The other descriptions describe different patterns: one implies the second language replaces the first as dominant, another suggests the first language stays dominant while the second is added without displacement (an additive pattern), and another envisions equal prestige for both languages in school. These reflect alternate bilingualism outcomes rather than the specific scenario highlighted here.
