The measure

What Proposition 58 did

Prop 58 ("English Proficiency. Multilingual Education.") was an initiative statute placed on the November 2016 ballot. It kept the goal of English proficiency for every student, but removed the requirement that schools reach it through English-only methods.

Background: Proposition 227 (1998)

In June 1998 California voters approved Proposition 227, "English for the Children", with about 61% of the vote. It declared that "all children in California public schools shall be taught English by being taught in English", and placed English learners in sheltered English immersion during a temporary transition period not normally intended to exceed one year.[6] Parents could request a waiver, but the effect was to end most bilingual programs in the state.

By 2016 that law was nearly two decades old. Prop 58's supporters argued it restricted the methods districts could use; opponents argued that it preserved parental choice. See the campaign.

What it did not do

Why it matters. By returning the decision to local districts, Prop 58 made it possible for the state to later adopt a multilingual policy vision. See looking ahead.
