TExES 257 Requirements 2026: Eligibility, Prerequisites & How to Qualify

Who Must Take the TExES 257 Exam

The TExES Health EC-12 (257) exam is the certification test the Texas Education Agency (TEA) requires for anyone seeking to teach health education across early childhood through grade 12 in Texas public schools. Whether you're finishing a traditional educator preparation program (EPP), completing an alternative certification route, or adding a health certification onto an existing teaching credential, this is the content exam TEA and the State Board for Educator Certification use to verify you know the subject matter well enough to teach it.

If you're still deciding whether this credential fits your career plans, it's worth reading a broader overview of what TExES 257 is and how it functions inside Texas's certification system before you commit to the requirements below.

Eligibility Basics: EPP Approval or TEA Approval

Unlike some national certifications that let anyone pay a fee and sit for the test, TExES 257 requires an approval step first. You must be approved to test either through your educator preparation program (a university certification program or an approved alternative certification program) or directly through TEA. This approval confirms you've met the coursework and program milestones tied to your certification path before Pearson will let you schedule an appointment.

Once approved, most candidates also need to plan for the pedagogy side of certification. A first Texas classroom certificate requires passing the PPR EC-12 (160) exam in addition to the content-area test, so treat TExES 257 as one piece of a two-exam certification requirement, not the whole picture.

Registration, Fees, and Test-Day Mechanics

TExES 257 is a computer-administered test (CAT) developed and administered by Pearson (Evaluation Systems) on behalf of TEA and the State Board for Educator Certification. It's delivered at Pearson VUE testing centers throughout Texas and at select locations nationwide, and it's offered by appointment year-round rather than on a handful of fixed dates.

• Exam fee: $136, with no separate member or non-member pricing tiers.
• Registration validity: Your registration window stays open for 170 days from the date you register.
• Withdrawal refund: If you withdraw before testing, you're refunded the exam fee minus a $25 processing charge.
• Appointment length: 5 hours total - 15 minutes for the CAT tutorial and compliance agreement, plus 4 hours 45 minutes of actual testing time.

For a full accounting of every fee, potential retake cost, and how they stack up against total certification spending, see the dedicated TExES 257 certification cost breakdown.

Exam Format and What It Tests

The exam contains 91 total questions: 90 selected-response items and 1 constructed-response question. Some administrations may also slip in unscored field-test items to help TEA calibrate future exams - you won't know which items are unscored, so treat every question as if it counts. Only the scored items feed into your final scaled score.

Because the constructed-response question requires human scoring in addition to the automated scoring of selected-response items, score reports take longer than a typical multiple-choice-only exam - expect roughly a four-week reporting cycle rather than same-day or next-day results.

Domain-by-Domain Breakdown

TEA organizes the content into five domains, and understanding their relative weight is essential for deciding where to spend your prep hours. For a deeper walkthrough of each competency and skill statement, the TExES 257 exam domains guide breaks every domain down further than this overview.

Notice that Domain V is worth as much as Domains III and IV combined. Many candidates focus almost exclusively on multiple-choice prep and shortchange the writing component - a mistake worth avoiding given how much of your final score rides on that one response.

Passing Score, Retakes, and Waivers

The passing score is 240 on a 100-300 scale. Under 19 TAC 151.1001, the selected-response portion is worth 72 points with an average raw cut around 41, while the constructed-response portion is worth 8 points with a cut of 5, for administrations beginning September 2, 2025. If you want the full mechanics of how raw points convert to the scaled score, the TExES 257 passing score guide walks through it in detail, and the difficulty guide puts that cut score in context against the exam's structure.

Because retakes cost time and money, it pays to review published outcome data before you sit for the first time. The TExES 257 pass rate analysis looks at statewide performance data so you can calibrate your own prep intensity realistically.

From Passing Score to a Texas Certificate

Passing TExES 257 doesn't hand you a certificate by itself - it's one requirement inside a larger certification process. After passing, your EPP or TEA processes the result alongside your other certification requirements, including the PPR EC-12 (160) pedagogy exam for first-time certificate holders. Once issued, a standard Texas certificate is valid for five years and renews through the ECOS system, requiring 150 continuing professional education (CPE) clock hours for classroom teachers during that renewal cycle.

If you're weighing whether the time and cost of this whole pathway make sense for your career goals, the ROI analysis on TExES 257 certification and the salary guide both look at the return side of that equation, while a look at TExES 257 jobs shows which districts and roles actually hire for this credential.

A Realistic Prep Timeline by Domain

Generic study advice rarely accounts for how lopsided TExES 257's domain weights are. Instead of splitting study time evenly across five domains, weight your schedule toward Domain II and reserve dedicated time for Domain V's writing practice.

For a more comprehensive walkthrough of preparation strategy, including how to structure practice tests around the constructed-response question, see the full TExES 257 study guide. You can also work through timed, domain-tagged questions directly on our practice test platform to see which content areas need the most attention before test day.

If You Were Planning to Take the Old 157

If your research turned up references to "TExES Health EC-12 (157)," note that this is the exam TExES 257 replaced. The 157 exam was last administered September 1, 2024, and could no longer be used for certification purposes after September 1, 2025. Any prep materials, study guides, or domain breakdowns tied to the old 157 numbering are now outdated - everything you need going forward should reference the redeveloped 257 exam and its current domain structure described above.
