- Mathematics is roughly 58 of 90 questions (64%), so it deserves nearly two-thirds of your study time.
- Science covers just 32 questions (36%) across four broad domains - breadth matters more than depth here.
- The exam uses selected-response, multiple-select, numeric entry, drag-and-drop, and drop-down items, not just standard multiple choice.
- You get 120 minutes for 90 questions, with no scheduled break, so pacing practice matters as much as content review.
Praxis 5028 Exam Overview
Praxis Early Childhood: Mathematics and Science (5028) is one of two subtests that make up the Praxis Early Childhood Assessment (5026), administered by Educational Testing Service (ETS). If you're preparing for the 5026 as a whole, you'll also sit for a companion subtest, but this guide focuses specifically on the mathematics and science portion - the one candidates most often underestimate because it sounds like "just content review" rather than a test of instructional judgment.
The subtest is computer delivered, either at an official test center or at home, and consists of 90 selected-response questions with a 120-minute time limit. That works out to a little over 78 seconds per question on average, though some items (especially numeric entry and drag-and-drop) will take longer than simple recall questions. Some administrations include unscored questions mixed in that don't count toward your score, so don't waste mental energy trying to guess which items are "real."
For a full breakdown of every content area tested, see the Praxis 5028 Exam Domains 2026: Complete Guide to All 2 Content Areas. This article focuses on how to actually prepare, week by week and topic by topic.
Domain Breakdown: Mathematics vs. Science
The single most important strategic fact about Praxis 5028 is the imbalance between its two domains. Mathematics is not a "co-equal" partner with science on this exam - it dominates.
| Domain | Approx. Questions | Approx. Weight |
|---|---|---|
| Domain 1: Mathematics | ~58 questions | 64% |
| Domain 2: Science | ~32 questions | 36% |
If you only take one strategic insight from this guide, it's this: a candidate who is excellent at science but shaky on fractions and algebraic thinking will struggle far more than one who has the reverse profile. Allocate your study hours accordingly - roughly two hours on math for every one hour on science, adjusted for your personal weak spots.
Key Takeaway
Spend the majority of your prep time on mathematics topics, not because science doesn't matter, but because math questions outnumber science questions by nearly two to one.
What to Master in Mathematics
The mathematics domain breaks into four content clusters. Each one shows up repeatedly in item banks, and each maps to how young children actually build number sense in early childhood classrooms.
Numbers and Operations: Whole Numbers
Expect questions on place value reasoning, counting strategies, composing and decomposing numbers, and the progression from concrete manipulatives to abstract notation.
- Base-ten thinking and regrouping in addition/subtraction
- Multiple strategies for the same operation (number lines, arrays, decomposition)
- Recognizing developmentally appropriate errors in student work
Numbers and Operations: Fractions
Fraction items test conceptual understanding - partitioning shapes, equivalent fractions, and comparing fractions using visual models - rather than rote algorithms.
- Area models, number lines, and set models for fractions
- Common early-childhood misconceptions (e.g., bigger denominator = bigger fraction)
- Connecting fraction concepts to measurement and sharing contexts
Algebraic Thinking
Early algebraic thinking in this age range means patterns, sorting, classifying, and understanding equality - not symbolic equations.
- Repeating and growing patterns
- The meaning of the equal sign in early math contexts
- Attributes, sorting rules, and simple functional relationships
Geometry, Measurement, and Data
This cluster covers shape properties, spatial reasoning, units of measurement, and interpreting simple graphs and data displays.
- 2D and 3D shape attributes and composition/decomposition of shapes
- Nonstandard vs. standard measurement units
- Reading and constructing simple bar graphs, tally charts, and picture graphs
For a deeper dive into how these four clusters interact with the science domains and how ETS weights specific subtopics, check the Praxis 5028 Exam Domains 2026 guide.
What to Master in Science
Science makes up about 32 questions, spread across four broad areas. Because the weighting is lower, your goal here isn't exhaustive depth - it's reliable coverage of each area so you're never blindsided by an entire domain.
Nature of Science and Engineering
Focuses on scientific inquiry practices appropriate for young learners: observation, questioning, simple investigations, and engineering design thinking.
- Steps of a simple scientific investigation
- Using tools and senses to gather data appropriately for age group
- Basic engineering design cycle: ask, imagine, plan, create, improve
Physical Science
Covers matter, forces, motion, and energy at a conceptual, hands-on level suited to early childhood classrooms.
- Properties of matter and simple states-of-matter changes
- Push/pull forces and simple machines
- Light, sound, and basic energy transfer concepts
Earth and Space Science
Tests understanding of weather, seasons, Earth materials, and basic astronomy concepts children can observe directly.
- Weather patterns and seasonal change
- Rocks, soil, and simple Earth materials
- Day/night cycle and observable sky patterns
Life Science
Covers living vs. nonliving distinctions, basic life cycles, habitats, and human body basics appropriate for young children.
- Plant and animal life cycles
- Basic needs of living things and habitat concepts
- Simple classification of organisms by observable traits
Question Formats and Test-Day Mechanics
Praxis 5028 isn't a pure multiple-choice test, and that surprises candidates who haven't seen the actual format. Expect a mix of:
- Standard single-answer selected response
- Multiple-select items (choose more than one correct answer)
- Numeric entry (typing in a calculated value)
- Drag-and-drop items (ordering steps or matching concepts)
- Graphic-selection items (clicking on a part of an image or graph)
- Drop-down items (choosing from an embedded menu within a sentence)
These formats matter because partial familiarity isn't enough - you need to practice the mechanics of each item type, not just the content. A candidate who knows fraction concepts cold but has never used a drag-and-drop interface under time pressure can still lose time fumbling with the interface on test day.
The test is computer delivered at a test center or at home, with most administrations including no scheduled break. Unscheduled breaks don't stop the clock, so plan your pacing with that in mind rather than assuming you'll get a built-in pause. If you want a detailed look at how difficult candidates generally find this pacing and format combination, see How Hard Is the Praxis 5028 Exam? Complete Difficulty Guide 2026.
Registration, Fees, and Score Reporting
Praxis 5028 has a $100.00 registration fee, which includes four free score recipients - meaning you can send your results to up to four institutions or states without paying extra. ETS also offers an official interactive practice test for $24.95, though it's provided free automatically when you register for the exam itself.
Scores are reported on a 100 to 200 scale. Because each certifying state sets its own qualifying score, there is no single universal "passing number" - you must confirm your specific state's requirement before you register. For a full walkthrough of scoring thresholds, visit Praxis 5028 Passing Score 2026: Exactly What You Need to Pass, and for a complete cost breakdown including the practice test option, see Praxis 5028 Certification Cost 2026: Complete Pricing Breakdown.
Key Takeaway
Confirm your state's specific qualifying score on the 100-200 scale before you register - passing "the test" and passing "for your state" are two different checkpoints.
Also worth tracking: ETS has announced new Elementary Education Fundamentals tests launching in spring 2026. If your state is reviewing licensure requirements, this could affect which exam you're ultimately required to take, so check current guidance before locking in your study plan. For scheduling specifics and testing windows, see Praxis 5028 Exam Dates 2026: Testing Windows, Deadlines & Scheduling.
A Study Timeline Built Around the 64/36 Split
Generic study advice (spaced repetition, timed drills, active recall) works, but only if it's mapped onto the actual weighting of this exam. Here's a sample structure that respects the 64% math / 36% science split rather than treating both domains equally.
Whole Numbers & Fractions
- Review base-ten reasoning and fraction models
- Take a timed set of numeric-entry practice questions
Algebraic Thinking & Geometry/Measurement/Data
- Practice pattern and shape-composition items
- Drill graphic-selection and drag-and-drop question types
Physical Science & Nature of Science/Engineering
- Review inquiry steps and simple engineering design cycles
- Study matter, forces, and energy at a conceptual level
Earth/Space & Life Science, Full Review
- Cover weather, seasons, life cycles, and habitats
- Take a full 90-question timed simulation under the 120-minute limit
Notice that math gets two full weeks of dedicated focus while science shares the remaining time - proportional to how the actual exam is weighted. If you're just getting oriented to the exam overall, the Praxis 5028 Study Guide 2026: How to Pass on Your First Attempt page and practice resources at our main practice test site are good starting points before you build out a full plan.
Common Mistakes That Cost Points
- Treating math and science as equal priorities. With a 64/36 split, under-preparing for math is the single most common way candidates lose points they didn't need to lose.
- Ignoring item-format practice. Multiple-select, drag-and-drop, and numeric entry items require interface familiarity, not just content knowledge.
- Assuming a break is built in. Most administrations have no scheduled break, and unscheduled breaks don't pause the clock - plan your pacing accordingly.
- Skipping the state score check. Because qualifying scores vary by state on the 100-200 scale, some candidates study to a generic target instead of their actual requirement.
- Studying content in isolation from classroom application. Since specifications were shaped by NCTM, NSTA, and NGSS-aligned reviewers, questions often frame content through a teaching lens, not a pure content-knowledge lens.

FAQs
The variety of formats - multiple-select, numeric entry, drag-and-drop, graphic-selection, and drop-down items - adds an interface-familiarity challenge on top of content knowledge, so practicing with those formats specifically is worth the time.
Mathematics accounts for approximately 58 of the 90 questions (64%), while science accounts for approximately 32 questions (36%), making mathematics the dominant study priority.
The official interactive practice test normally costs $24.95, but it's provided free automatically once you register for the $100.00 exam fee.
Most administrations include no scheduled break, and any unscheduled break you take does not stop the test clock, so factor that into your pacing strategy.
Scores are reported on a 100 to 200 scale, but each certifying state sets its own qualifying score, so you must confirm your specific state's requirement before registering.
Passing Praxis 5028 on your first attempt comes down to respecting its actual structure: heavy math weighting, lighter but still essential science coverage, unfamiliar item formats that need dedicated practice, and a state-specific passing score you must confirm ahead of time. Build your prep around those realities rather than generic exam advice, and you'll walk into test day prepared for what this specific subtest actually asks of you.
