Requirements

What you need to teach English in the U.S.

The minimum requirement to teach English at a U.S. language institute or newcomer program is a bachelor’s degree in any area and a 120-hour TEFL/TESOL certificate from an accredited institute. A state-issued teaching license is only required for K-12 public school positions — not for adult ESL at private language institutes, community programs, Business English courses, or IELTS/TOEFL exam preparation.

This is what makes TESOL so appealing for career-changers: all you need to upgrade your bachelor’s degree is an accredited TEFL/TESOL certification. Previous ESL teaching experience is not required, though the U.S. job market is competitive and most applicants have some experience. A great way to build experience is to volunteer in a newcomer ESL program, teach abroad for a year, or get started as an online ESL teacher.

ESL teaching jobs in the United States are available to U.S. citizens and established immigrants with the right to work. For general TESOL/TEFL/TESL concepts, see the TESOL guide.

Where to Teach

Three U.S. job paths for TESOL-certified teachers.

1
Private Language Schools

Accredited language schools offer ESL immersion programs to international students who pay premium tuition. Most are located in the largest U.S. cities and many are operated by international chains. 1–2 years of teaching experience is preferred, and many successful candidates have taught English abroad first. Language schools get busy in the summer months — a good time to apply for part-time jobs if you’re newly certified.

2
Community Centers & Newcomer Programs

Community centers across the U.S. offer affordable ESL classes for immigrants and refugees. These programs are ideal for newly certified teachers looking to build experience before moving to a paid position at a language school or going abroad. Some programs pay hourly; others offer Practicum-hour credit in exchange for volunteer teaching. This is the most accessible entry point into the U.S. market.

3
Business English & Exam Prep

IELTS, TOEFL, and Business English positions pay the highest hourly rates in the U.S. adult ESL market — up to $50/hr. These roles typically require 3+ years of ESL teaching experience and specialist training. OnTESOL offers 20-hour Teaching IELTS and Teaching Business English specialist courses for teachers building toward these opportunities.

K-12 licensed teachers: earn CEUs

OnTESOL is accredited by ACCET, a U.S. Department of Education-recognized agency. Licensed teachers can earn Continuing Education Units (CEUs) to maintain their state teaching license — and qualify for ESL roles in newcomer and bilingual programs. Teaching ESL in a U.S. public school still requires a state teaching license or M.Ed., but a TESOL certification significantly enhances effectiveness and employability in those roles.

How to Apply

How to find your first U.S. ESL job.

OnTESOL graduates receive free, lifetime job assistance including a resume review, cover letter support, interview preparation, and access to our international and online TEFL job board. During the U.S. job interview, employers commonly ask candidates to demonstrate a grammar or vocabulary lesson plan — which is exactly where OnTESOL’s lesson-planning Lab Assignments earn their keep.

Three tips from OnTESOL graduates who landed their first U.S. ESL job:

  • Volunteer first. Starting as a volunteer in a newcomer program shows employers you care about teaching. It builds classroom confidence and gives you a genuine story to tell in interviews.
  • Consider teaching abroad. Teachers with international experience have a real advantage applying to U.S. language schools — they understand the immersion student experience firsthand.
  • Master lesson planning. U.S. language schools demand more professionalism than many programs abroad. Get comfortable using Communicative Language Teaching frameworks (PPP, ESA, TBL) before applying.

I have a better understanding of how students learn and feel much better prepared now to teach English in the United States. The grammar and phonology modules were great in-depth reviews. The methodology module was an excellent step-by-step guide of how to plan a lesson. My tutor, Aaron Marques, gave very insightful comments from his personal teaching experience.

Common Questions

Teach English in the U.S. — answered.

Everything U.S. applicants ask about accredited certification, CEUs, and state licensing.

Yes. The minimum requirement to teach English at a U.S. language institute is a bachelor’s degree in any area and a 120-hour TESOL or TEFL certificate from an accredited institute. Depending on the employer, previous teaching experience or a completed Practicum may also be preferred. With an OnTESOL certificate, you can teach in the U.S., go abroad, teach online, or qualify for professional ESL teaching jobs worldwide.

To teach in U.S. public schools, the minimum requirement is a state-issued teaching license or an M.Ed. (Master’s in Education). A TEFL or TESOL certification alone isn’t sufficient, but it’s highly recommended for positions that involve teaching English to non-native speakers, such as newcomer programs or bilingual education. TESOL certification complements your teaching credentials and enhances your employability in those roles.

ACCET (Accrediting Council for Continuing Education and Training) is a U.S. Department of Education-recognized accrediting agency. Accredited institutions must meet high-quality standards for curriculum, assessment, and training delivery. Choosing an ACCET-accredited TEFL/TESOL institute means your certification is validated in the U.S. and internationally. OnTESOL is the only online TEFL/TESOL institute accredited by ACCET, so graduates earn CEUs recognized by U.S. state licensing boards.

Pay varies by market. Accredited language schools and newcomer programs typically pay $22–$26/hr. Online ESL teaching ranges from $15 to $30/hr depending on the platform. Business English and IELTS/TOEFL prep pay up to $50/hr for experienced teachers. For salaried positions, ESL teachers start around $45,000/year, with the top 25% earning $69,000+ as they gain experience and specialization.

Yes. OnTESOL’s 120-hour Advanced TESOL/TEFL Certificate earns 12 U.S. Continuing Education Units (CEUs), and each 20-hour specialist course earns an additional 2 CEUs. Because OnTESOL is ACCET-accredited (U.S. Dept. of Education recognized), the CEUs are validated toward state teaching license renewal. Requirements vary by state — check with your state licensing board to confirm acceptance.

The Practicum is not required to complete your TESOL/TEFL certification with OnTESOL, but separate Practicum modules are available for graduates who want supervised teaching practice on their credentials. OnTESOL has partnered with ELI, an ACCET-accredited language school based in San Francisco, to offer the Practicum for US$500. OnTESOL graduates in other U.S. locations are responsible for finding an ESL school for the Practicum; OnTESOL provides the guidelines, moderates the reports, and issues the final Practicum certification. Experienced ESL teachers may complete this module at their current workplace.

ESL teaching jobs in the U.S. are available to U.S. citizens and established immigrants with the right to work (green card holders, valid work visas). The U.S. does not typically sponsor work visas for adult ESL teaching roles at language institutes. If you’re not yet eligible to work in the U.S., consider teaching English abroad first — OnTESOL graduates qualify for ESL positions in 20+ countries through our lifetime job assistance program.
