The LBS1 endorsement lets you teach English as a second language in Illinois public schools

The LBS1 endorsement is an add-on to your Illinois teaching license that authorizes you to teach English as a second language (ESL) to students who are learning English. It does not replace your base teaching license — you need a valid Illinois teaching certificate first, then add the LBS1 to it. Schools hire teachers with this endorsement to work with English learners in separate ESL classes, in mainstream classrooms as co-teachers, or in pull-out instruction.

The endorsement is issued by the Illinois State Board of Education (ISBE). To get one, you complete coursework in ESL methods and linguistics, pass a content exam, and submit your paperwork to ISBE. The process typically takes several weeks after you submit your process.

Key Takeaways

  • You must hold a valid Illinois teaching certificate before you can add an LBS1 endorsement to it.
  • The endorsement requires completion of specific coursework in ESL instruction, linguistics, and assessment of English learners.
  • You must pass the Illinois Content Area Test for ESL (the ICTS ESL exam) before ISBE will issue the endorsement.
  • Most teacher preparation programs and universities in Illinois offer LBS1 endorsement programs, either as part of a master's degree or as a standalone certificate.

What coursework and exams you need

Illinois requires specific content in your coursework before you sit for the exam. The coursework typically covers second language acquisition theory, ESL teaching methods, assessment of English learners, and linguistics. Most programs require between 12 and 18 semester hours of coursework, though the exact amount varies by university.

After you finish the coursework, you take the Illinois Content Area Test for ESL (ICTS ESL). This is a computer-based exam administered by the Illinois Department of Financial and Professional Regulation (IDFPR). You must pass this exam before ISBE will process your endorsement process. The exam covers ESL instruction methods, language development, assessment, and cultural competence.

Some universities bundle the coursework and exam into a single program, while others let you take courses and register for the exam separately. Check with the program you choose about whether they handle exam registration or whether you register directly with IDFPR.

Where to complete the endorsement program

Most Illinois universities and colleges offer LBS1 endorsement programs. These include large state universities like Northern Illinois University, Southern Illinois University, and the University of Illinois, as well as private institutions and smaller regional colleges. Many programs are offered both in person and online, so location does not necessarily limit your options.

Some programs offer the endorsement as part of a master's degree in education or ESL, while others offer it as a standalone certificate that adds to your existing license. A standalone certificate is usually faster and less expensive if you already have a teaching degree and license. A master's degree takes longer but may lead to salary increases or additional career options.

Before enrolling, confirm that the program is approved by ISBE and that it covers all the content areas required for the ICTS ESL exam. Ask the program whether they provide exam preparation materials or whether you need to study separately.

How to submit your endorsement process to ISBE

Once you have completed your coursework and passed the ICTS ESL exam, you submit your endorsement process to ISBE. You will need your passing exam score, official transcripts from your university showing completion of the required coursework, and your current Illinois teaching certificate number.

ISBE accepts applications through their online portal. You create an account, upload your documents, and pay the endorsement fee (the amount varies and should be confirmed on the ISBE website). After you submit, ISBE reviews your materials, which typically takes two to four weeks. Once approved, ISBE issues an updated teaching certificate that includes the LBS1 endorsement.

Keep copies of all documents you submit, including your exam score report and transcripts. If ISBE requests additional information, having these copies on hand speeds up the process.

The difference between LBS1 and other ESL-related credentials

Illinois also recognizes the Transitional Bilingual Education (TBE) endorsement, which is different from LBS1. TBE authorizes you to teach academic content in a student's native language while they learn English, whereas LBS1 focuses on teaching English itself. Some teachers hold both endorsements. There is also the Bilingual Education endorsement, which requires fluency in a specific language and covers both content instruction and language development.

If you speak another language fluently and want to teach content in that language, a bilingual or TBE endorsement may be a better fit. If your goal is to teach English language skills specifically, LBS1 is the right choice. Some schools need both types of teachers, so your decision may also depend on what positions are available in your area.

Cost and timeline

The cost of an LBS1 program varies widely depending on whether you choose a master's degree or a standalone certificate, and whether you attend a public or private institution. Standalone certificates at public universities typically cost between $3,000 and $8,000 in tuition, while master's programs can range from $15,000 to $40,000 or more. The ICTS ESL exam fee is separate and should be confirmed with IDFPR.

The timeline also varies. A standalone certificate program can often be completed in one to two years if you attend part-time while teaching. A master's degree typically takes two to three years. The exam itself is usually available within a few weeks of registration, so the main time factor is completing the coursework.

Some school districts offer tuition reimbursement or professional development funds for teachers who pursue endorsements, so check with your employer about whether they can help cover costs.

Frequently Asked Questions

Do I need the LBS1 endorsement to teach ESL in Illinois?

Yes, Illinois requires an LBS1 endorsement to teach ESL in public schools. Private schools may have different requirements, so check with the specific school. If you teach ESL without the endorsement, you are teaching outside your license authorization.

Can I get the LBS1 endorsement if I don't have a bachelor's degree in education?

You must hold a valid Illinois teaching certificate to add the LBS1 endorsement. If you have a bachelor's degree in another field, you can pursue an alternative certification program to get your initial teaching license, then add the LBS1. Some universities offer combined programs that lead to both.

How long does it take ISBE to issue the endorsement after I submit my process?

ISBE typically processes endorsement applications within two to four weeks of receiving all required documents. If documents are missing or incomplete, the timeline extends. Contact ISBE directly if your process has been pending longer than four weeks.

Can I teach ESL while I'm working on the LBS1 endorsement?

No, you cannot teach ESL without the endorsement on your license. However, you may be able to work in other roles such as ESL aide, tutor, or instructional assistant while completing the program. Check with your school district about what positions are available.

Does the LBS1 endorsement expire or need to be renewed?

The LBS1 endorsement is part of your Illinois teaching certificate and follows the same renewal cycle as your base license. Illinois teaching certificates are typically valid for five years and must be renewed through continuing professional development. Check the ISBE website for current renewal requirements.
