ESL (English as a Second Language) teachers play a critical role in ensuring that multilingual students have equitable access to instruction and the opportunity to meet high academic standards. To meet both state requirements and federal expectations under the Every Student Succeeds Act (ESSA), ESL teachers must demonstrate specialized preparation, certification, and ongoing professional learning.
State Certification Requirements
ESL teachers are required to hold:
- A valid state teaching certificate
- A state-issued ESL/ESOL endorsement or certification, as defined by the State Department of Education
- Completion of approved coursework in areas such as:
- Second language acquisition
- Linguistics and language development
- ESL instructional methods and assessment
- Culturally and linguistically responsive teaching
- Successful completion of state-required assessments, background checks, and licensure requirements
- Compliance with license renewal and continuing education expectations
These requirements ensure that ESL teachers are legally authorized and professionally prepared to provide language instruction and support to multilingual learners.
Alignment with ESSA
Under ESSA, districts are required to ensure that multilingual students are taught and supported by appropriately certified and qualified educators. ESL teacher qualifications align with ESSA expectations by ensuring that educators:
- Are properly certified to provide ESL services, not just experienced or trained informally
- Can deliver high-quality language instruction aligned to English Language Proficiency (ELP) standards
- Support students’ English language development and academic achievement across content areas
- Use data-informed practices to monitor language growth and instructional effectiveness
- Collaborate with classroom teachers to ensure meaningful access to grade-level curriculum
ESSA emphasizes equity, accountability, and access—making certified ESL educators essential to compliance and student success.
