A Pennsylvania middle grades guide for the ETS selected-response and numeric-entry format, the 50/50 math-science split, calculator use, and core science domains.
Praxis 5155 preparation should balance math and science equally while building speed with numeric-entry questions, calculator decisions, standards-based math, scientific inquiry, life science, physical science, Earth and space science, and technology impacts.
Use these official structure points to organize Pennsylvania Grades 4-8 Mathematics and Science study.
ETS lists selected-response and numeric-entry questions for Praxis 5155.
The subtest is approximately 80 minutes.
The current ETS listing and study companion show 80 questions.
Mathematics and Science each account for 40 questions, or 50% of the exam.
The exam gives mathematics and science equal weight. Candidates should avoid spending all review time on the harder personal subject and instead maintain steady practice across both 40-question halves.
An on-screen scientific calculator is provided, but ETS notes that some problems are faster without it. Practice estimation, setup, arithmetic, fractions, ratios, and percent problems so calculator use stays purposeful.
The science content includes inquiry, methodology, tools, data interpretation, life science, physical science, Earth and space science, environmental topics, energy, natural resources, biotechnology, and public health applications.

Praxis Pennsylvania Grades 4-8 Core Assessment: Mathematics and Science 5155 is the math and science subtest in the Pennsylvania Grades 4-8 Core Assessment sequence. ETS lists an approximately 80-minute computer-delivered exam with 80 selected-response and numeric-entry questions, and an on-screen scientific calculator is provided.
The current study companion divides the test evenly between Mathematics and Science, with 40 questions, or 50%, in each area. The mathematics section reflects Pennsylvania mathematics standards, Pennsylvania Core Mathematics Standards, and middle level mathematics preparation guidance, while the science section reflects Pennsylvania Science and Technology and Engineering Education standards and national science teaching standards. Preparation should cover quantitative problem solving, calculator judgment, scientific inquiry, life science, physical science, Earth and space science, and science-technology-society topics.
ETS lists the subtest as approximately 80 minutes.
The current ETS listing and study companion list 80 questions.
ETS lists selected-response and numeric-entry questions.
Yes. ETS states that an on-screen scientific calculator is provided.
Mathematics accounts for 40 questions or 50%, and Science accounts for 40 questions or 50%.
Assign equal study blocks to mathematics and science, then track missed questions by topic instead of by broad subject alone.
Practice exact entry for whole numbers, decimals, fractions, rates, percentages, measurements, and scientific calculations.
Cycle scientific inquiry, physical science, life science, Earth and space science, and science-technology-society topics with short recall checks.
Use mixed 80-question practice to rehearse pacing, calculator decisions, question flagging, and switching between math and science reasoning.
Use the guide to self-serve, or talk to a coordinator if you need help mapping timelines, official requirements, or troubleshooting day-of logistics.
