For 2026 planning, the official Science 7-12 (236) framework is a 140-question selected-response exam delivered in a 5-hour appointment (4 hours 45 minutes testing) with a 240 scaled passing score and a $116 fee. The framework weights Physics and Chemistry at 20% each, Scientific Inquiry and Processes at 10%, Earth's History and Earth Systems at 9%, Cell Structure, Heredity/Evolution, and Diversity of Life at 8% each, Interdependence/Environmental Systems and the Solar System/Universe at 6% each, and Science Learning, Instruction and Assessment at 5%. Earth and space science is tested within this exam; there is no separate Texas earth-science certification test for the 7-12 science certificate.

Sample TExES Science 7-12 (236) Practice Questions

Try these sample questions to test your TExES Science 7-12 (236) exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1A teacher wants students to identify the dependent variable in an experiment testing how light intensity affects plant growth. Which quantity is the dependent variable?
A.The intensity of the light
B.The height of the plant after two weeks
C.The type of plant species used
D.The amount of water given each day
Explanation: The dependent variable is the measured response that may change as a result of the manipulated (independent) variable. Plant height is measured in response to light intensity, so it is the dependent variable.
2Which laboratory practice best protects students when working with a strong acid such as concentrated hydrochloric acid?
A.Adding water to the acid in a graduated cylinder
B.Wearing goggles and adding acid slowly to water
C.Smelling the container directly to identify the acid
D.Storing the acid next to a strong base on the same shelf
Explanation: Safety requires eye protection and always adding acid to water (never water to acid) because the dilution is exothermic and can cause violent spattering. This minimizes heat-driven splashes.
3A student reports a measured value of 9.79 m/s^2 for gravitational acceleration when the accepted value is 9.81 m/s^2. This comparison is a measure of the result's:
A.Precision
B.Accuracy
C.Sensitivity
D.Resolution
Explanation: Accuracy describes how close a measured value is to the accepted or true value. Comparing 9.79 with the accepted 9.81 evaluates accuracy, not consistency among repeated trials.
4Which statement best distinguishes a scientific theory from a scientific hypothesis?
A.A theory is a guess, while a hypothesis is proven fact
B.A theory is a well-substantiated explanation supported by extensive evidence, while a hypothesis is a testable proposed explanation
C.A theory cannot be tested, but a hypothesis can
D.A hypothesis becomes a law, and a law becomes a theory
Explanation: A scientific theory is a broad, well-supported explanation of natural phenomena backed by a large body of evidence. A hypothesis is a specific, testable proposed explanation that experiments are designed to evaluate.
5Which of the following is the correct number of significant figures in the measurement 0.004560 km?
A.Three
B.Four
C.Six
D.Seven
Explanation: Leading zeros are not significant, but the digits 4, 5, 6 and the trailing zero after the decimal are. That gives four significant figures: 4, 5, 6, and 0.
6A car travels 150 meters in 10 seconds at constant velocity. What is its average speed?
A.1.5 m/s
B.15 m/s
C.150 m/s
D.1500 m/s
Explanation: Average speed equals distance divided by time, so 150 m / 10 s = 15 m/s. The constant-velocity condition means instantaneous speed equals the average.
7According to Newton's second law, if the net force on an object doubles while its mass stays constant, the acceleration will:
A.Remain the same
B.Double
C.Be cut in half
D.Become zero
Explanation: Newton's second law states F = ma, so acceleration is directly proportional to net force when mass is constant. Doubling the force doubles the acceleration.
8A 2 kg object is lifted to a height of 5 meters near Earth's surface. Using g = 9.8 m/s^2, what is its gravitational potential energy relative to the starting point?
A.10 J
B.49 J
C.98 J
D.490 J
Explanation: Gravitational potential energy is PE = mgh = 2 kg x 9.8 m/s^2 x 5 m = 98 J. The energy is measured relative to the reference height where the object started.
9Which statement correctly describes the relationship between the frequency and wavelength of a wave traveling at constant speed?
A.They are directly proportional
B.They are inversely proportional
C.They are equal in magnitude
D.They are unrelated
Explanation: Wave speed equals frequency times wavelength (v = f x lambda). At constant speed, increasing frequency decreases wavelength, so they are inversely proportional.
10A series circuit contains two resistors of 4 ohms and 6 ohms connected to a 20 V battery. What is the current through the circuit?
A.0.5 A
B.2 A
C.5 A
D.10 A
Explanation: In a series circuit, total resistance is the sum: 4 + 6 = 10 ohms. By Ohm's law, I = V/R = 20 V / 10 ohms = 2 A throughout the circuit.

Frequently Asked Questions

How many questions are on the TExES Science 7-12 (236) exam?

The official test page lists 140 selected-response (multiple-choice) questions. The appointment is 5 hours, with 4 hours 45 minutes of actual testing time after the tutorial and compliance agreement.

What passing score do I need for the TExES Science 7-12 (236)?

The passing standard is a scaled score of 240. TExES scaled scores range from 100 to 300, so aim for consistent performance across all ten domains rather than targeting a guessed raw-score cutoff.

How much does the TExES Science 7-12 (236) exam cost?

The current computer-administered testing fee is $116. Always confirm the current fee during registration because Texas educator testing fees can change.

Which domains are weighted most heavily on the Science 7-12 (236)?

Physics and Chemistry are weighted most heavily at 20% each, followed by Scientific Inquiry and Processes at 10% and Earth's History and Earth Systems at 9%. The four life-science domains and the solar system domain make up the remainder.

Does the TExES Science 7-12 (236) include earth and space science?

Yes. Earth's history and Earth systems (9%) plus components of the solar system and the universe (6%) are tested directly within the Science 7-12 (236) exam, so there is no separate earth-science test for the 7-12 science certificate.

How should I study for the TExES Science 7-12 (236) effectively?

Prioritize physics and chemistry since they total 40% of the exam, then reinforce life science and earth/space science. Use full-length timed practice, review missed items by domain, and master core problem-solving in motion, energy, stoichiometry, genetics, and the rock cycle.
