- Frequently Asked Questions
- TExES 164 is a supplemental certification - it adds bilingual authorization to an existing Texas teaching certificate, it does not stand alone.
- For Spanish bilingual roles, districts require both exam 164 and the BTLPT 190 before you can be assigned to a bilingual classroom.
- House Bill 2 waives the $116 exam fee and the $78 certification application fee for eligible first-time candidates.
- The pathway sunsets: August 31, 2027 is the last day to test on 164/190, and September 1, 2028 is the last day districts can use those scores for certification.
What the TExES 164 Actually Unlocks
The TExES Bilingual Education Supplemental (164) is not a certificate you can hold by itself. It is a supplemental credential layered onto a base Texas teaching certificate (early childhood, elementary generalist, ESL, special education, and so on). Passing it - combined with the required companion exam for Spanish, the BTLPT 190 - allows the Texas Education Agency to add a bilingual education endorsement to your certificate. That endorsement is what actually opens the door to bilingual classroom assignments, because Texas districts are legally required to staff bilingual programs with teachers who hold this specific authorization.
If you are researching this exam because you want to know what jobs it leads to, the honest answer is: it does not create a new job category by itself. It removes a legal barrier that would otherwise keep you out of bilingual classrooms, dual-language programs, and bilingual specialist roles that already exist in nearly every large and mid-size Texas district. For a full breakdown of what the credential is and how it is structured, see TExES 164 Certification and What Is TExES 164?.
Job Titles That Require or Prefer This Certification
Once the bilingual endorsement is on your certificate, you become eligible for a specific set of classroom and support roles that districts cannot legally assign to teachers without it. These typically include:
- Bilingual Education Teacher - self-contained or content-area instruction delivered in both L1 and L2, most common in elementary grades.
- Dual Language Program Teacher - one-way or two-way dual language models where instructional time is split between Spanish and English.
- Bilingual/ESL Instructional Specialist - campus or district-level roles supporting curriculum, coaching, and compliance for bilingual programs.
- Bilingual Special Education Teacher - for candidates who hold both a special education base certificate and the 164 supplemental.
- Newcomer or Transitional Bilingual Program Teacher - serving recently arrived students who need first-language academic support while acquiring English.
Every one of these roles draws directly on the four competency areas tested by exam 164, which is why hiring committees and principals ask about the exam by name during interviews, not just whether you "have a bilingual certification."
Who Is Hiring Bilingual-Certified Teachers
Because Texas state law requires bilingual education programs in districts with sufficient numbers of English learners, demand for the 164-endorsed teacher pool is structural rather than seasonal. Hiring sources generally fall into three categories:
- Independent School Districts (ISDs): The largest employer group, particularly districts with high English Learner (EL) enrollment in urban and border regions.
- Charter Schools: Many operate dual-language or bilingual strands and recruit certified bilingual teachers directly, sometimes through the certification-by-exam route described in the eligibility rules.
- Regional Education Service Centers and District Support Roles: Bilingual specialists, instructional coaches, and program coordinators often must hold the same base certification plus the 164 endorsement, even though they are not full-time classroom teachers.
If you are still confirming your eligibility route - educator preparation program approval, out-of-state credentialing, or certification-by-exam - the detailed breakdown at TExES 164 Requirements 2026: Eligibility, Prerequisites & How to Qualify walks through each pathway before you register.
Key Takeaway
Bilingual teaching positions are frequently posted with language like "bilingual certification (164) required or in progress," meaning some districts will hire before you pass, provided you are approved to test and actively working toward the exam.
How the Exam Domains Map to Daily Job Duties
The exam framework defines a single domain - Bilingual Education - weighted at 100% and subdivided into four competencies. These are not abstract test categories; they mirror exactly what a bilingual teacher is expected to do in a Texas classroom.
Domain 1: Foundations of Bilingual Education, Bilingualism and the Learning Environment
Covers program models (transitional, dual language, maintenance), legal foundations, and how to structure a classroom environment that supports two languages simultaneously.
- Directly relevant to interview questions about which program model a school uses
Domain 2: First-Language and Second-Language Acquisition and Development
Tests understanding of how students acquire L1 and L2, including stages of language development that inform daily lesson pacing and error correction decisions.
- Used constantly when differentiating instruction for students at different proficiency stages
Domain 3: Development and Assessment of L1 Literacy and Biliteracy
Covers biliteracy development and how to assess reading and writing skills across both languages - a competency principals often probe in demo lessons.
- Ties directly to how bilingual teachers select and interpret literacy assessments
Domain 4: Content-Area Instruction in L1 and L2
Focuses on delivering math, science, and social studies content across both languages - the daily instructional reality of a bilingual classroom.
- Most frequently referenced during walkthroughs and instructional coaching cycles

Why This Is a Paired Credential, Not a Standalone Job Ticket
A common misunderstanding among job seekers is treating the 164 as a complete bilingual credential. For Spanish bilingual assignments, TEA pairs exam 164 with the BTLPT 190, which assesses Spanish language proficiency itself. You need both scores on file before TEA can add the bilingual endorsement to your certificate - and before a district can legally assign you to a bilingual classroom. Job postings that list "bilingual certified" as a requirement are implicitly referencing both exams together.
This pairing also affects how you should sequence your prep. Some candidates study for the pedagogy content in 164 first because it overlaps with coursework they've already completed, then shift focus to Spanish proficiency for the 190. Others do the reverse. Either way, treat the two exams as one certification project with two checkpoints, not two unrelated hurdles.
The Retirement Timeline and Why It Matters for Job Seekers
TEA is phasing out this exam pathway in favor of a replacement credential, TExES 165 Bilingual Education Spanish Supplemental, which launches September 1, 2026. This matters directly to your job search timeline:
- August 31, 2027 is the last date candidates can sit for exam 164 (and the paired 190).
- September 1, 2028 is the last date districts and TEA can apply or recommend candidates for certification using 164/190 scores.
If you are currently in an educator preparation program or eyeing a bilingual teaching job that requires this specific endorsement, these dates should shape when you register and test - not just when you feel "ready." Waiting too long could push you into the newer TExES 165 pathway instead, which has its own separate requirements. Full scheduling detail is available at TExES 164 Exam Dates 2026: Testing Windows, Deadlines & Scheduling.
| Factor | Detail |
|---|---|
| Exam format | 80 selected-response questions, may include unscored field-test items |
| Appointment length | 5 hours |
| Passing score | 240 (scale of 100-300) |
| Standard fee | $116 (waived for eligible first attempts under HB 2, along with the $78 application fee) |
| Attempt limit | 5 attempts, 30-day wait between attempts; waiver required beyond that |
| Companion exam (Spanish) | BTLPT 190 |
| Last testing date | August 31, 2027 |
| Last certification-use date | September 1, 2028 |
Getting Job-Ready: A Domain-Focused Study Plan
Because the exam has only one weighted domain broken into four competencies, your prep schedule should be organized around mastering each competency in sequence rather than spreading effort evenly across unrelated subject areas. A short, focused plan works better than an open-ended study calendar.
Foundations and Program Models
- Review Domain 1 concepts: program types, legal mandates, classroom environment design
- Compare your target districts' program models against what you're studying
Acquisition and Development
- Study Domain 2 stages of L1/L2 acquisition
- Practice applying acquisition theory to sample classroom scenarios
Literacy and Biliteracy Assessment
- Focus on Domain 3 assessment tools and biliteracy progression
- Take a full-length practice set and review missed items by competency
Content-Area Instruction and Final Review
- Work through Domain 4 content-area delivery strategies
- Run a full timed practice exam under 5-hour conditions

You can also build familiarity with the question style using realistic practice questions on the main practice test platform.
Cost of Certification Versus Career Access
Job seekers often weigh the cost and effort of a supplemental exam against the roles it unlocks. With the House Bill 2 fee waiver in place for eligible first-time candidates, the direct financial barrier to entry is lower than it has been historically. What remains is the study investment and, for Spanish bilingual roles, coordinating your 164 prep with BTLPT 190 readiness.

Key Takeaway
Before applying to bilingual teaching positions, confirm you're approved to test through your educator preparation program or an alternative route, since approval status - not just passing - is what allows district HR to move your application forward.
Frequently Asked Questions
Not by itself. For Spanish bilingual assignments, you also need a passing score on the BTLPT 190. TEA adds the bilingual endorsement to your existing base teaching certificate only after both scores are on file.
Many districts post openings for candidates who are "certified or in progress," meaning you may be considered while approved to test, but you'll need to complete certification requirements before receiving the full bilingual endorsement.
August 31, 2027 is the last day to test on exam 164 and BTLPT 190, and September 1, 2028 is the last day those scores can be used for certification. After that, candidates move to the TExES 165 pathway instead.
The exam has 80 selected-response questions administered over a 5-hour appointment, with a passing scaled score of 240 out of a 100-300 range. Score reports break down performance by competency as well as overall.
TEA allows up to five attempts on a certification exam, with a mandatory 30-day wait between attempts. Beyond five attempts, a test-limit waiver from TEA is required.
