What is TESOL vs. ESL vs. TEFL Degree?

A TESOL, ESL, and TEFL degree all prepare individuals to teach English to non-native speakers, but each serves a different audience and career goal.

TESOL (Teaching English to Speakers of Other Languages) is the broadest, combining domestic and international teaching contexts. It’s ideal for educators who want to teach English either abroad or to immigrants and international students in English-speaking countries.

ESL (English as a Second Language) degrees focus specifically on teaching within English-speaking nations like the U.S., Canada, or the U.K. ESL teachers often work in K–12 schools, adult literacy programs, and community centers. In the U.S., the Bureau of Labor Statistics (2025) reports an average pay of $59,950 per year for adult ESL instructors.

Meanwhile, TEFL (Teaching English as a Foreign Language) degrees or certificates are geared toward those who plan to teach English in non-English-speaking countries such as Japan, Spain, or South Korea. TEFL credentials are often shorter, career-entry routes rather than full academic degrees, making them more flexible for travel-oriented professionals.

Those seeking faster study options can also look into accelerated ESL programs online for a quicker transition into teaching roles.

Which program (TESOL, ESL, TEFL) matches my career goals and location?

The right program depends on where you want to teach and the type of students you aim to work with. 

• TESOL is the most versatile option—it qualifies you to teach English both in the U.S. and abroad. It’s well-suited for those seeking long-term careers in academia, international education, or curriculum development. TESOL graduates often hold advanced degrees and earn between $45,000 and $70,000 annually in the U.S.
• ESL degrees are best for teaching English within English-speaking countries. They prepare educators for public school systems, adult literacy centers, and community programs. The BLS (2025) notes that adult ESL teachers earn about $59,950 per year, with employment spread across education and nonprofit sectors.
• TEFL is ideal for those who want to teach English in non-English-speaking nations. It’s typically a certificate rather than a degree, allowing teachers to work in language institutes or private schools worldwide. Global salaries vary widely—from $600 to $4,000 per month, depending on region and experience.

The chart below highlights the most common majors among ESL teachers, showing that English-related fields dominate the profession and reinforce how academic background often aligns with one’s teaching pathway. Professionals comparing global teaching and academic credentials might also look into what is the difference between BA and MBA, since many TESOL graduates later pursue management or administrative roles in education institutions abroad.

What are the typical entry requirements for a TESOL / ESL / TEFL degree or certificate?

Entry requirements for TESOL, ESL, and TEFL programs differ by academic level and country, but all emphasize English proficiency and foundational education.

TESOL degree requirements:

• A bachelor’s degree in English, linguistics, or education (minimum GPA 2.5–3.0).
• English proficiency proof (TOEFL or IELTS) for non-native speakers.
• Some graduate programs—like those at New York University and University of Pennsylvania—require prior teaching experience or coursework in linguistics.
• Application materials often include a statement of purpose, recommendation letters, and transcripts.

ESL degree requirements:

• High school completion for undergraduate entry; a bachelor’s degree for graduate or certification tracks. According to Zippia (2025), 70% of ESL teachers have a bachelor’s degree, while 19% hold a master’s.
• Education-focused coursework, including pedagogy and applied linguistics.

TEFL certification requirements:

• Minimum of a high school diploma or bachelor’s degree (varies by provider).
• No teaching experience needed; programs usually last 120 hours.
• Applicants must demonstrate native or near-native fluency in English.

Applicants deciding between shorter certificates and advanced degrees may also compare outcomes similar to those in is it better to have a paralegal certificate or degree, since that same cost-versus-depth consideration applies here—certificate programs offer speed, while degrees deliver long-term career flexibility.

How long does each program take, and what formats are offered?

Program length and format vary significantly between TESOL, ESL, and TEFL degrees depending on level and delivery mode. 

A TESOL degree typically takes two to four years to complete: four years for a bachelor’s and one to two years for a master’s. Many U.S. universities now offer hybrid or fully online TESOL programs, making them accessible for working educators. TESOL International Association (2024) estimates that 120,000–140,000 certified TESOL educators currently teach in the U.S., reflecting strong institutional demand for degree-qualified teachers.

ESL programs follow traditional academic timelines: four years for a bachelor’s and two years for a master’s. Flexible learning options are also growing. Some universities provide accelerated or distance-based tracks through online ESL teaching certification programs to allow teachers to qualify faster without leaving their jobs.

TEFL certifications are shorter—usually 120-hour courses completed in 4 to 12 weeks, available both online and in-person. These are ideal for those seeking immediate overseas teaching placements, especially in Asia, Europe, and Latin America.

What will I actually learn in a TESOL/ESL/TEFL program?

Students enrolled in TESOL, ESL, and TEFL programs develop a blend of linguistic knowledge and teaching competence tailored to their target learners. These programs share several foundations but differ in depth, academic focus, and delivery format.

TESOL programs typically include:

• Second Language Acquisition and Linguistics
• English Grammar and Phonology for Teachers
• Curriculum Design and Language Assessment
• Cross-Cultural Communication and Pedagogy
• Teaching Practicum or Classroom Observation

ESL degrees often cover:

• Educational Psychology and Bilingual Education
• Literacy Development and Reading Instruction
• Classroom Management and Inclusive Teaching
• Lesson Planning and Technology Integration
• Student Assessment and Feedback Strategies

TEFL certifications emphasize:

• Adapting to International Classroom Settings
• Grammar Review and Error Correction
• Engaging Learners with Interactive Activities

Together, these subjects build strong communication, planning, and instructional skills. The chart below illustrates the top employer-valued skills for ESL teachers, confirming how academic coursework translates into practical classroom competencies. If you’re pursuing graduate-level teaching or leadership roles, you might also explore the difference between MA and MFA, since TESOL’s theoretical focus differs from an MFA’s creative or literary orientation.

How much does each program cost, and what kinds of financial aid or scholarships exist?

The cost of TESOL, ESL, and TEFL programs depends on the level, format, and country where you study. According to CollegeTuitionCompare (2025), undergraduate TESOL or ESL degrees average $10,000 per year for in-state students and $24,000 for out-of-state students. Graduate programs are slightly lower, averaging $12,000 in-state and $21,000 out-of-state. These totals exclude additional costs such as books, certification exams, or practicum fees.

TESOL certificates are the mid-range option, typically costing $1,000–$2,500, while TEFL courses are far cheaper—usually $300–$2,000, depending on the provider and location. CELTA, a highly regarded Cambridge credential, costs about $2,500–$3,200 for full certification. Many institutions now offer flexible financing, employer tuition reimbursement, and scholarships for international educators.
