Exam Basics at a Glance
Before you memorize a single formula, lock in the mechanics of the Praxis Algebra I (5162) test itself. ETS administers this exam through its own network of test centers, including Prometric-affiliated sites and university-based locations, and also offers at-home online proctoring for candidates who prefer to test remotely. The exam is computer delivered, contains 60 questions (a mix of scored and unscored pretest items, so the exact count per domain can shift slightly between forms), and gives you 150 minutes to finish.
That works out to roughly two and a half minutes per question on average, though some items - especially multi-step algebraic justification or systems-of-equations problems - will eat more time than quick numeric-entry questions. Pacing awareness matters as much as content mastery. For a deeper breakdown of how test-day difficulty actually feels in practice, see How Hard Is the 5162 Exam? Complete Difficulty Guide 2026.
Domain Breakdown: What's Actually Tested
The 5162 blueprint is organized into three content domains, and they are not weighted evenly. Understanding the weight distribution should directly shape how you allocate study time.
Domain 1: Principles of Algebra (38%, ~23 questions)
This is the dominant domain by a wide margin, covering the core algebraic reasoning skills that show up across nearly every other topic on the test.
- Rewriting expressions in equivalent forms (factoring, expanding, simplifying)
- Polynomial arithmetic - addition, subtraction, multiplication, and division
- Creating and solving equations and inequalities from context
- Justifying each step of a solution process algebraically
- Solving systems of equations and systems of inequalities
- Average rate of change over an interval
- Slope and intercepts of linear relationships
Domain 2: Functions (30%)
This domain tests your ability to interpret, build, and transform functions across multiple representations - tables, graphs, equations, and verbal descriptions.
- Identifying domain, range, and function notation
- Comparing linear, quadratic, and exponential function behavior
- Interpreting key features of graphs (intercepts, intervals of increase/decrease, end behavior)
- Modeling real-world situations with an appropriate function type
Domain 3: Number and Quantity; Probability and Statistics (32%)
The final domain blends foundational number-sense reasoning with data interpretation - two areas that often get under-studied relative to their combined weight.
- Properties of real numbers, exponents, and radicals
- Units and quantity reasoning in applied problems
- Measures of center and spread in data sets
- Basic probability, including compound and conditional situations

Question Formats You'll See On Screen
5162 is not a plain multiple-choice test. ETS uses a variety of interactive formats, and knowing the mechanics of each one before test day removes a layer of unnecessary friction.
- Selected-response: select one answer, or select one or more answers from a list
- Numeric-entry: type an exact numeric value into a box
- Fraction-entry: enter a fraction in a specific numerator/denominator field
- Drag-and-drop: move labels, values, or expressions into place
- Table-grid: fill in or select values within a grid structure
- Text-completion: complete a sentence or statement with the correct term or value
- Select-an-area: click a specific region of a graph or figure to answer
Because these formats are unusual if your only test-taking experience is standard multiple choice, spend at least one practice session interacting with each format type rather than only reviewing content. Muscle memory for the interface saves real minutes on exam day.
Calculator and On-Screen Tools
An on-screen graphing calculator is provided throughout the entire test - you don't bring your own device, and you don't need to request access to it separately. This matters for how you approach Functions questions in particular: instead of manually sketching behavior, you can graph a function directly and read off intercepts, intervals, or end behavior.
Key Takeaway
Practice using an on-screen graphing calculator interface (not a physical TI-84) before test day so the tool feels familiar rather than distracting during timed conditions.
Registration, Fees, and Retake Rules
The administrative details are simple once you see them laid out, but they're easy to get wrong if you're mixing up 5162 with another exam that shares a similar name elsewhere. Here's what actually applies to Praxis Algebra I (5162):
| Item | Detail |
|---|---|
| Registration fee | $130 flat rate - same price for every candidate, no tiers |
| Score recipients included | Four free score reports sent with registration |
| Retake wait period | 28 days minimum between attempts |
| Score validity | Reportable for 10 years from test date |
| Delivery options | Test centers (including Prometric-affiliated sites) or at-home online proctoring |

Scoring Facts to Memorize
Scores are reported on the standard Praxis 100-200 scale. Here's the detail that trips up a lot of candidates: there is no single universal passing score for 5162. Each state or licensing agency sets its own required score, so the number you need depends entirely on where you plan to use the certification.
For the specifics on how state cutoffs are structured and where to find yours, read 5162 Passing Score 2026: Exactly What You Need to Pass. If you want context on how outcomes tend to trend across test-takers, the 5162 Pass Rate 2026: What the Data Shows article walks through what's publicly known.
Final-Week Review Plan
In the last stretch before your test date, resist the urge to study everything evenly. Given that Principles of Algebra carries the heaviest weight, your review time should mirror that imbalance rather than splitting three ways.
Principles of Algebra Deep Review
- Redo polynomial arithmetic and equivalent-expression problems until they're automatic
- Drill systems of equations and inequalities, including justification steps
Functions Practice
- Practice reading graph behavior using the on-screen graphing calculator
- Compare linear, quadratic, and exponential models side by side
Number/Quantity and Statistics Cleanup
- Review exponent and radical rules, measures of center, and basic probability
- Run a full-length timed practice set covering all three domains
Light Review and Logistics
- Skim a formula sheet, confirm test-center or online-proctor requirements
- No new content - just format familiarity and rest
Notice this schedule allocates roughly double the review time to Principles of Algebra compared to either of the other two domains - a direct reflection of the 38% weighting. If you want a broader timeline that starts weeks earlier, the 5162 Study Guide 2026: How to Pass on Your First Attempt lays out a full multi-week structure.
High-Yield Formulas and Topics
Keep this list visible during your last few practice sessions - these are the concepts that recur across multiple question formats on 5162.
- Slope formula: change in y over change in x, and its connection to average rate of change on a non-linear interval
- Factoring patterns: difference of squares, trinomial factoring, and grouping for polynomial simplification
- Systems solving methods: substitution and elimination, plus graphical interpretation of solution sets for systems of inequalities
- Function notation: evaluating f(x) at given inputs and interpreting transformations (shifts, stretches, reflections)
- Exponent rules: product, quotient, and power rules, plus rational and negative exponents
- Statistics basics: mean, median, mode, range, and interpreting spread in a data set
- Probability: independent vs. dependent events and basic compound probability calculations
Content across all three domains aligns to the NCTM CAEP Standards (2020) and the NCTM Principles and Standards for School Mathematics (2000) rather than any single state's curriculum, so questions tend to test conceptual reasoning over rote procedure. That's part of why a general practice test run-through on our main practice test platform is useful - it exposes you to the reasoning style examiners favor, not just the raw math.
If any part of the terminology around this exam still feels unclear - what the certification actually represents, or how it differs from related credentials - the What Is 5162? and 5162 Meaning articles cover that ground directly. You can also run a diagnostic practice session on our practice test hub to see which of these three domains needs the most attention before you finalize your review plan.
Frequently Asked Questions
The test contains 60 questions total, which includes both scored and unscored pretest items. Because of this, the exact number of questions within any single domain can vary slightly from one test form to another.
You have 150 minutes to complete all 60 questions. The test is delivered entirely on computer, whether you sit at a physical test center or test at home through online proctoring.
The registration fee is a flat $130 for every candidate - there are no membership discounts or tiered pricing. This fee includes sending your scores to four recipients at no extra charge.
Principles of Algebra, which makes up 38% of the test (about 23 questions), should get the most attention since it carries significantly more weight than either Functions (30%) or Number and Quantity; Probability and Statistics (32%).
You can retake the exam, but you must wait at least 28 days between attempts. Your scores remain reportable to certifying states for 10 years, so there's no immediate expiration pressure once you do pass.
