q2 i? CTC data indicate vacancy rates and educators without the required BLA credential in bilingual classrooms persisted from 2020 through 2023, signaling continued unmet demand. → Grayson 2026 (2)

q2 · i? · design · r2
Statewide analysis finding: while the state nears the Global 2030 target of 2,000 new bilingual authorizations annually, assignment-linking data "have not been updated since 2018–19," so leaders cannot determine whether investments increase program capacity.
"publicly available statewide data linking bilingual authorizations to classroom assignments have not been updated since 2018–19"

CTC statewide data reported in the analysis show vacancies and misassignment in bilingual classrooms "persisted from 2020 through 2023," which the authors read as continued unmet demand for BLA educators.
"statewide data from the Commission on Teacher Credentialing (CTC) indicate that the rates of vacancies and instances of educators without the required BLA credential in bilingual classrooms persisted from 2020 through 2023, signaling continued unmet demand for BLA educators"
