To be an ESL teacher, you need at least a bachelor's degree, but a master's degree is often preferred for adult education teachers. Degrees are usually earned in education, adult education and bilingual education. Licensure and certification requirements vary by state. Some requirements include passing praxis exams, earning bilingual authorization, and obtaining cross-cultural language and academic development (CLAD) certificates. Teachers need a variety of skills, including creativity, instructional skills, communications skills, cultural sensitivity, and computer software skills.

How to Become a Certified ESL Teacher

The following are steps you can take to become a certified ESL teacher:

Step 1: Earn a Bachelor's Degree

To obtain a teaching position, applicants are generally required to hold a bachelor's degree, though a master's degree is highly valued among many employers. Prospective public school or adult ESL teachers should take courses in linguistics and theories of second language acquisition. ESL teachers are not required to be fluent in a second language. Most teacher education programs require the completion of an internship, commonly known as student teaching. All states offer an alternative route to certification for people who have a bachelor's degree in a field other than education.

Step 2: Obtain Certification

Requirements for ESL certification vary largely by state. Teaching in a PK-12 school requires the specific ESL credentials to work with English language learners (ELLs). Obtaining a TESOL (Teaching English to Speakers of Other Languages) certificate may provide more teaching opportunities. Many degree programs focused on education are now offering ESL endorsements.

Step 3: Seek Professional Development

To keep up with the latest research and improve their teaching skills, many adult literacy teachers take professional development classes. Public school teachers are also required to meet professional growth requirements to keep their teaching licenses current. Each state sets its own mandatory minimum hours of professional development and other certificate renewal requirements. Some states have several certificates and authorizations available for ESL teachers.

Step 4: Earn a Master's Degree

ESL teachers of adult students in colleges or universities may be required to obtain a master's degree. Master's degrees in adult education prepare prospective teachers to use successful teaching techniques and to work with students from various backgrounds. In some programs, teachers may specialize in adult basic education, secondary education, or English as a second language (ESL).

To stay informed about vital topics in the ESL teaching field, consider joining a professional organization, such as TESOL International Association, that serves teachers of students from diverse language backgrounds.

Step 5: Career Advancement

ESL teachers may have a variety of advancement opportunities depending on the program with which they are affiliated. As part-time teachers are often hired, a part-time position can advance into a full-time position as experience is gained. Depending on the program, there may be options available to advance to program director or program coordinator. There are also non-profit programs available that may allow the ESL teacher to move into designing program materials or work on the research side of the field.
