What is on the TExES Science 7-12 Exam?
The TExES Science 7-12 exam focuses on more advanced topics, theories, and skills in the field than the ones designed for lower grades (the TExES Science 4-8). Candidates may be asked questions with more advanced vocabulary, calculations, and concepts.
The TExES test for Science 7-12 contains ten broad domains that correspond to eleven different education standards to assess candidates' knowledge. Within each domain, the test evaluates candidates on multiple competencies that focus on various topics within the domain. These different competencies test candidates' knowledge of vocabulary, scientific theories, processes, and more. The table below outlines the approximate percentage of the exam that each domain makes up.

Science Learning, Instruction and Assessment
Domain I: Scientific Inquiry and Processes
The scientific inquiry and processes domain covers three different competencies.
The first competency examines candidates' ability to choose and manage learning activities that keep students and organisms, equipment, technologies, and materials safe. Candidates will answer questions about procedures and techniques for analyzing data, incorporating safe practices in planning all instructional abilities and designs, and identifying potential hazards in a lab setting.
The second competency tests candidates' knowledge of science, scientific inquiry, and the concepts that are common across all fields of science. Test-takers may be asked about topics such as procedures for scientific investigations, limitations to science, and theory vs. hypothesis.
The final competency examines the history of science and the interactions and impacts of science with students and society. Questions may address topics in the changing nature of science, the role science plays in global issues, and scientific ethics.
Domain II: Physics
The physics domain covers several competencies that cover major areas in physics. Candidates will answer questions concerning the following areas:
Motion (in 1D and 2D)
Laws of motion
Gravitational and electromagnetic forces
Applications of electricity and magnetism
Conservation of energy and momentum
Laws of thermodynamics
Fundamental concepts of quantum physics
In this section, candidates will not only need to know theories, laws, and major concepts of the field, but they will also need to solve problems and analyze data. This may require candidates to use and interpret illustrations or graphs to show proficiency in these domains.
Domain III: Chemistry
Candidates will probably use the provided periodic table to complete all the questions in the chemistry domain. This domain addresses the following competencies:
Characteristics of matter and atomic structure
Properties of gases
Properties and characteristics of ionic and covalent bonds
Chemical equations and chemical reactions
Types and properties of solutions
Energy transformations in physical and chemical processes
Nuclear fission, nuclear fusion, and nuclear reactions

Acids, bases, and their reactions
Candidates are asked to analyze data, solve problems, and apply their knowledge of major concepts in the field. Questions will also address major chemical models and chemical laws.
Domain IV: Cell Structure and Processes
The fourth domain tests candidates' knowledge of cell structure and processes. Questions pertain to four different competencies.
Candidates will show they have a firm understanding of the structure and function of biomolecules, the specialized parts of cells used to perform specific functions, cell life processes, and the growth and development of specialized cells, tissues, organs, organ systems, and organisms.
Also, they may be asked specific questions concerning the levels of cellular organization, anaerobic vs. aerobic respiration, enzyme function, photosynthesis, and different cell types, such as eukaryotic vs. prokaryotic cells. These questions may require information about viruses, plant cells, and animal cells.
Domain V: Heredity and Evolution of Life
The heredity and evolution of life domain also cover four competencies.
The first competency addresses the structure and function of nucleic acids and their use in genetics. Candidates may need to answer questions about the structure of DNA and RNA, the control of genomics in various types of cells, the cause and effects of mutations, and human karyotypes.
The second competency examines candidates' knowledge of traits being passed to future generations. Questions may ask about meiosis vs. mitosis, laws of probability for genotypic and phenotypic frequencies, environmental factors on the expression of traits, and more.
The third competency explores the theory of biological evolution. This section tests knowledge of natural selection, competition, effects of selection, and speciation.
The final competency tests candidates' knowledge of the evidence for evolutionary change throughout history. Topics for these questions may pertain to theories of extinction, how environmental change affects mutations and adaptations, and the different pieces of evidence used to support change in populations and species, such as the fossil record and DNA sequences.
Domain VI: Diversity of Life
The diversity of life domain tests candidates' understanding of the following competencies:
Similarities and differences of living organisms/taxonomic systems
How living systems are found within other living systems with boundaries and limits
Processes used for homeostasis
Relationship of biology and behavior
Candidates may be asked questions on specific topics, such as classification schemes, systems in plants and animals, internal feedback mechanisms, innate vs. learned behaviors, and links between behavior and natural selection. They may need to know specific concepts, including altruism, imprinting, convergent traits, and homologous traits. Candidates must answer questions about comparing and contrasting various organisms, concepts or theories, and must demonstrate skills in taxonomic classification.
Domain VII: Interdependence of Life and Environmental Systems
The seventh domain covers the interdependence of life and environmental systems. The section examines candidates' knowledge and understanding of three different competencies.
The first competency tests the understanding of various relationships, including abiotic and biotic factors in ecosystems, habitats, and biomes. Questions may include topics in the sources and flow of energy at trophic levels, in biogeochemical cycles, and limiting factors.
The second competency examines the interdependence and interactions of organisms in various types of ecosystems. Candidates should understand concepts such as niche, food chains, interspecific interactions, biodiversity, the role of plants, and more.
The final competency asks about carrying capacity and how it relates to changes in ecosystems and populations. Candidates may need to compare population dynamics, explain how carrying capacity affects dynamics, and analyze density-dependent and density-independent factors. Some of these factors may include natural events, birth rates, death rates, and more. They may also need to interpret survivorship curves, patterns of distribution, and other data.
Domain VIII: Earth's History and the Structure and Function of Earth Systems
The domain about the Earth's history and the structure and function of Earth systems tests prospective teachers' knowledge of:
