How to Register

  1. 1
    Get approval to test

    You must be approved before you can register for a TExES exam. If you are in an educator preparation program, your program approves you. Candidates who are not in a program follow the approval routes described on the Registration Information page.

  2. 2
    Register and pay online

    Create your account and register at tx.nesinc.com. Pay by Visa or MasterCard (including debit cards that carry the logo and need no PIN), Apple Pay or Google Pay. Cash and checks are not accepted.

  3. 3
    Schedule your appointment

    After registering, you pick a test center and a date. Appointments are available year round on a first-come, first-served basis. Your registration is valid for 170 days, so schedule and test within that window.

  4. 4
    Prepare with the official manual

    Read the free preparation manual for exam 236. It lists every competency and includes sample questions with explanations. Request alternative testing arrangements early if you need them, because approval takes time.

Fees

$116. Additional fees may apply. Exam registration fees are paid online by Visa or MasterCard, Apple Pay or Google Pay, and payment processing is provided by Texas.gov, which charges a processing fee that is not refundable. Your registration is valid for 170 days from the date of issue. If you do not take the exam within 170 days, or you withdraw within that time, the registration expires and you receive no refund or credit of any kind. Fees can change, so confirm the amount when you register.

Test day

Report to the test center 15 minutes before your scheduled testing time.

Bring two pieces of original, unexpired identification printed in English in the name used in your testing account. Each must show your name, and the set must include a recent photograph and your signature. Photocopies and digital IDs are not accepted.

At check-in, staff verify your ID and collect your digital signature and photograph.

Cell phones, electronic devices, watches, handwritten or printed materials, bags, food and drink, and most headwear must be stored in a locker outside the testing room. Calculators are prohibited except for the exams that allow them. Breaking the test site rules can void your scores.

Dress in layers, since the temperature of the center may not be under the control of the test administrators, and wear soft-soled shoes to keep the room quiet. Children are not allowed in the testing center.

Scoring

Total exam scores are reported on a scale of 100 to 300. The passing score is 240.

Scores are available at 10:00 p.m. Central time on the published score report dates. Your report shows Passed or Not Passed and your total scaled score, and for most exams it also shows how you did by domain and competency.

There is no way to predict the exact number of correct answers needed to pass, because each exam has several versions that are adjusted to be comparable.

Who Takes the TExES Science 7-12 (236)?

Prospective Texas teachers. For those preparing to teach general science in grades 7 through 12.

Candidates whose educator preparation program requires it. Confirm with your program that exam 236 is the one you need before you register.

How to Prepare for TExES Science 7-12 (236)

  1. 1
    Start with the official preparation manual

    It is the only study material the Texas Education Agency endorses. Read the competencies for exam 236 and mark each one you cannot yet explain.

  2. 2
    Study by domain weight

    Give the most time to Physics (about 20%), but cover every domain.

  3. 3
    Physics and chemistry are 40% together

    Each is about 20%, more than any biology or Earth science domain, so start there.

  4. 4
    Cover all sciences

    Biology is spread across four domains and Earth and space across two, so review each topic list.

  5. 5
    Leave room for a retake

    You can retake an exam after 30 days, and you cannot register again until your results have posted. Book your first attempt early enough that a second one still fits your deadline.
