What TX PACT 739 Actually Is
TX PACT: Physics: Grades 7-12 (739) is a content-knowledge exam required by the Texas Education Agency (TEA) as part of the Pedagogy and Professional Responsibilities admission process for certain candidates entering educator preparation programs (EPPs). It is administered by Pearson through Pearson VUE test centers, and it exists to confirm that a candidate has the physics content mastery needed before an EPP admits them into physics teacher preparation.
It's easy to confuse this exam with other Texas educator tests, so it's worth being precise: TX PACT 739 is not the same as TExES Physics/Mathematics 243, which is the certification exam candidates take later in their preparation program. PACT 739 is a pre-admission or transfer-admission screening tool. If you want the full breakdown of how this credential is defined and where it sits in the Texas educator pipeline, see TX PACT 739 Certification and TX PACT 739 Requirements 2026.
Exam Format and Registration Mechanics
TX PACT 739 is a computer-administered exam made up of 125 selected-response questions. Some of those items may be unscored field-test questions used to evaluate future exam content, so you won't necessarily know which questions count toward your score. Total testing time is 3 hours and 45 minutes, but plan for a 4-hour appointment overall - the extra 15 minutes covers the tutorial and the compliance agreement you must complete before the test begins.
During the exam, you're given an on-screen scientific calculator and a Constants and Formulas reference sheet. This is a meaningful advantage, but don't over-rely on it: the reference does not contain every formula you might need, so you still have to know derivations and relationships cold, especially in mechanics and electromagnetism. Electricity and magnetism questions specifically use conventional current and assume you're comfortable applying the right-hand rule - a detail that trips up candidates who only studied electron-flow conventions.
- Base exam fee: $106
- Passing scaled score: 240
- Testing window: Candidates must schedule and take the exam within 170 days of registration
- Availability: Year-round by appointment, in Texas and nationwide
- Retakes: At least 30 days must pass between attempts, and prior results must post to ECOS before rescheduling; affiliated candidates also need EPP retest approval

Key Takeaway
Register with your 170-day testing window in mind - build your study plan backward from your intended test date rather than treating registration as a formality.
The Five Domains You'll Be Tested On
The official TX PACT 739 framework organizes content into five domains spanning 14 competencies. All domain weights below are approximate, but they tell you exactly where to concentrate your effort. A detailed walkthrough of every competency lives in TX PACT 739 Exam Domains 2026: Complete Guide to All 5 Content Areas; here's the shape of what you're facing.
Domain 1: Nature of Science (14%)
Covers scientific methodology, measurement, experimental design, and the reasoning skills that underpin physics as a discipline.
- Understanding how evidence supports or refutes physical models
Domain 2: Mechanics (28%)
The largest domain by far, covering kinematics, dynamics, forces, energy, momentum, and rotational motion.
- Expect this domain to dominate your study time given its weight
Domain 3: Electricity and Magnetism (22%)
Covers circuits, fields, and electromagnetic interactions - remember that questions assume conventional current and the right-hand rule.
- Practice field-direction problems using right-hand-rule conventions specifically
Domain 4: Waves (14%)
Covers wave behavior, sound, and optics, including reflection, refraction, and interference concepts.
- Connect wave math back to the formulas provided in the reference sheet
Domain 5: Modern Physics (22%)
Covers quantum and relativistic concepts, but also includes thermal energy and thermodynamics - a combination candidates often overlook.
- Don't skip thermodynamics thinking this domain is purely "modern" physics
| Domain | Approximate Weight |
|---|---|
| Nature of Science | 14% |
| Mechanics | 28% |
| Electricity and Magnetism | 22% |
| Waves | 14% |
| Modern Physics | 22% |

Who Takes TX PACT 739 and Why
TX PACT 739 is taken by candidates seeking admission or transfer admission into a Texas EPP's physics teacher preparation track. To be eligible, EPP-admission or transfer candidates need either a bachelor's degree or final-semester standing, plus a TEA ID. The exam is a gate for anyone whose GPA falls below 2.5 or who has fewer than 15 relevant subject-area semester credit hours - a way for TEA and EPPs to verify content readiness before candidates begin formal teacher preparation.
Importantly, PACT testing taken for EPP admission or for charter-school assignment purposes is exempt from the standard five-attempt limit that applies to many Texas educator exams. However, candidates in intensive pre-service pathways remain subject to that five-attempt cap, so the exemption isn't universal - check your specific pathway before assuming unlimited retakes.
School districts and charter schools hiring physics teachers are ultimately the downstream audience for this credentialing process, since PACT-cleared candidates move on to certification testing and classroom placement. If you're weighing whether pursuing this pathway makes sense for your career plans, Is the TX PACT 739 Certification Worth It? Complete ROI Analysis 2026 and TX PACT 739 Jobs both dig into that question in more detail.
How It Fits the Physics/Mathematics Route
Some candidates pursue a combined PACT Physics/Mathematics pathway, which requires passing both Physics 739 and Mathematics 735. If your EPP has you on this dual-subject track, you'll need to plan study time and testing appointments for both exams - and given the 170-day scheduling window and 30-day retake spacing, sequencing matters. Sitting for both exams too close together without a study buffer between them can backfire if one subject needs more review time than the other.
This dual-credential route is distinct from single-subject PACT physics admission, and it's also distinct from certification testing further down the line. Keep the sequence straight: PACT is about EPP admission; TExES Physics/Mathematics 243 is the later certification step. Don't let the naming similarity between these programs cause you to study the wrong content or miss a deadline.
Preparing With the Domain Weights in Mind
Because Mechanics carries the heaviest weight at 28%, and Electricity and Magnetism plus Modern Physics each sit at 22%, an efficient study plan allocates time proportionally rather than treating all five domains equally. A simple weighted approach might look like this:
Mechanics Deep Dive
- Work through kinematics, dynamics, energy, and rotational motion problems
- Practice using the on-screen calculator and Constants and Formulas reference under timed conditions
Electricity and Magnetism
- Drill circuit analysis and field problems using conventional current and the right-hand rule
Modern Physics
- Cover quantum concepts alongside thermal energy and thermodynamics - don't treat these as separate topics
Waves and Nature of Science
- Round out optics, sound, and scientific methodology competencies
This kind of weighted scheduling - spending more calendar time on higher-percentage domains - is one of the few generic study principles worth borrowing here, and it only works if it's mapped directly onto TX PACT 739's actual domain weights rather than applied generically. For a structured week-by-week plan built specifically around this exam's competencies, see TX PACT 739 Study Guide 2026: How to Pass on Your First Attempt. A condensed reference of formulas, conventions, and domain reminders is also available in the TX PACT 739 Cheat Sheet 2026.
Practicing under realistic conditions matters too - running through timed, exam-style questions on our practice test platform before test day helps you get comfortable with the 125-question, 3-hour-45-minute format so pacing doesn't become a surprise during your actual appointment.
Key Takeaway
Allocate roughly proportional study time to each domain's weight - Mechanics deserves the most hours, but don't neglect Modern Physics's thermodynamics content just because it seems like an afterthought.
