What Is a 5162, Exactly?
When people search "what is a 5162," they're almost always asking about Praxis Algebra I (5162), a subject-area licensure test administered by Educational Testing Service (ETS). It is one of the Praxis Subject Assessments that states and licensing agencies use to confirm a candidate's readiness to teach a specific content area - in this case, secondary-level algebra. The number 5162 is simply the test code ETS assigns to this particular assessment inside its much larger Praxis testing catalog, which covers everything from elementary education to world languages.
It's worth being precise here because "5162" isn't a unique identifier across every industry - plenty of unrelated codes and credentials float around online. On this site, and in every article linked below, 5162 refers exclusively to Praxis Algebra I. If you're comparing prep resources, make sure they're describing this exact test and not a similarly numbered credential from a different field.
Who Takes This Test and Why
There is no formal prerequisite baked into the test itself - ETS doesn't require a specific degree before you can register. In practice, though, most examinees have already completed a bachelor's program with an emphasis in mathematics or mathematics education, since the content assumes real fluency with algebraic reasoning rather than a beginner's introduction to the subject.
The most common use case is an Algebra I add-on endorsement. That means a teacher who is already certified in another area - general middle school math, another science discipline, or even a different secondary subject - takes 5162 specifically to add authorization to teach Algebra I to their existing license. School districts sometimes need this coverage quickly, particularly in secondary math departments where scheduling gaps open up. Understanding your specific state's rules matters here, and that's covered in more depth in our 5162 Requirements 2026 guide, since each certifying agency sets its own passing score and eligibility rules on top of the ETS baseline.
Key Takeaway
If you're already a licensed teacher looking to add Algebra I authorization, 5162 is very likely the specific test your state wants - confirm the required scaled score with your licensing agency before you register.
Exam Format and Delivery
Praxis Algebra I is delivered by computer, either at an ETS-affiliated test center - including Prometric locations and university testing sites - or through at-home online proctoring if that option fits your situation better. Both delivery paths use the same content and time limit, so the choice comes down to convenience rather than difficulty.
The test consists of 60 questions completed in 150 minutes. That total includes both scored questions and unscored pretest items that ETS uses to evaluate future test forms, which is why the exact number of questions in any single content category can shift slightly from one test form to another. Don't be alarmed if your form has a question or two more or less in a given domain than what you studied against - the underlying percentage weighting stays consistent.
Question formats go well beyond simple multiple choice. You'll encounter:
- Selected-response items where you choose one answer
- Selected-response items where you choose one or more answers
- Numeric-entry and fraction-entry questions
- Drag-and-drop items
- Table-grid questions
- Text-completion items
- Select-an-area questions
An on-screen graphing calculator is provided throughout the entire test, so you don't need to bring your own device or memorize calculator shortcuts from a different model. Getting comfortable with that specific on-screen tool before test day is one of the more overlooked parts of preparation - muscle memory with an unfamiliar calculator interface under time pressure can cost you minutes you don't have.
What's Actually on the Test
5162 is organized into three content domains, and the weighting is not evenly split. Understanding this weighting is the single most useful thing you can do before you start studying, because it tells you where your review hours should actually go.
| Domain | Weight | Approx. Questions |
|---|---|---|
| Principles of Algebra | 38% | ~23 |
| Functions | 30% | ~18 |
| Number and Quantity; Probability and Statistics | 32% | ~19 |
Domain 1: Principles of Algebra (38%)
This is the single largest domain by a wide margin, and it deserves proportionally more of your study time than the other two combined would suggest at first glance. Candidates need to be fluent, not just familiar, with:
- Rewriting algebraic expressions in equivalent forms
- Polynomial arithmetic - adding, subtracting, multiplying, and factoring
- Creating and solving equations and inequalities from context
- Justifying each step of a solution process, not just arriving at an answer
- Systems of equations and systems of inequalities
- Average rate of change
- Slope and intercepts, including their real-world interpretation
Domain 2: Functions (30%)
This domain tests how well you understand functions as objects with behavior - not just as formulas to plug numbers into. Expect questions on identifying and interpreting different function types, translating between representations (tables, graphs, equations, verbal descriptions), and analyzing how functions behave and transform.
Domain 3: Number and Quantity; Probability and Statistics (32%)
This combined domain rounds out the exam with number sense, quantitative reasoning, and foundational statistics and probability concepts. It's a broader mix than the other two domains, so candidates sometimes underestimate how much ground it covers relative to its single label.

Registration, Fees, and Scoring Mechanics
Registering for 5162 is straightforward, but a few mechanical details matter:
- Fee: $130, a single flat price with no separate member or non-member tier - everyone pays the same amount.
- Score recipients: Registration includes four free score reports sent to institutions or agencies of your choice.
- Retakes: If you don't pass, you must wait 28 days before retesting.
- Score validity: Praxis scores remain reportable for 10 years, so a passing score doesn't expire quickly if your licensing plans change.
- Scoring scale: Results are reported on the standard Praxis 100-200 scaled range. There is no universal passing number - each state or licensing agency sets its own cutoff, so you must confirm the requirement with the agency you're submitting scores to.
Because the passing threshold is state-specific rather than fixed by ETS, it's worth checking the exact number your state requires before you assume a "good" score is automatically a passing one. We break this down agency by agency in 5162 Passing Score 2026: Exactly What You Need to Pass. If you're budgeting for the full process, including any retake costs, 5162 Certification Cost 2026: Complete Pricing Breakdown lays out the full financial picture.
Key Takeaway
The $130 fee is flat for everyone, but your actual "pass" number depends entirely on your state - verify it before test day rather than after.
A Domain-Aware Way to Prepare
Generic study advice - flashcards, timed drills, review sessions - only helps if it's pointed at the right targets. Given that Principles of Algebra alone accounts for 38% of the test, a preparation plan that spends equal time on all three domains is already working against the test's own weighting.
Principles of Algebra
- Drill polynomial arithmetic and factoring until it's automatic
- Practice writing and solving equations/inequalities from word problems
- Rehearse justifying each algebraic step out loud, not just computing the answer
Functions
- Practice moving between graph, table, and equation representations of the same function
- Review function transformations and behavior analysis
Number and Quantity; Probability and Statistics
- Refresh core probability and statistics concepts
- Practice quantitative reasoning items under time constraints
Format and Full Runs
- Practice drag-and-drop, table-grid, and numeric/fraction-entry items specifically
- Take full-length timed runs using the on-screen graphing calculator
Since the content is aligned to NCTM's CAEP Standards and its Principles and Standards for School Mathematics rather than any one state's curriculum, questions tend to test conceptual understanding over rote procedure - another reason surface-level memorization tends to underperform on this particular test.
