What Does the SAT Actually Test? The 29 Skills Explained
The digital SAT tests specific, learnable skills across Reading and Writing and Math. Every question maps to a skill type — here's exactly how the test is structured.

The 29 SAT Skills
The complete reference list of every skill on the digital SAT — name, domain, and what each one asks you to do. Use it when reviewing practice tests.
Why Am I Stuck at the Same SAT Score?
If your SAT score isn't moving, you almost certainly have a skill gap — not a motivation gap. Here's how to identify exactly what's holding your score back.
What Should I Study for SAT Math First?
Start with linear equations. They appear on virtually every SAT and connect to almost every other math skill. Here's the right order to study SAT Math for the fastest score improvement.
How to Improve Your SAT Score When You Have No Time
Short on time before the SAT? Stop reviewing everything. Find your top three skill gaps and drill those. Here's how to do it in 10 hours or less.
How to Prepare for the SAT in 8 Weeks
A concrete 8-week plan built around skill gaps, not generic review. Three phases: baseline, skill building, and practice tests. No filler.
SAT Prep for Students Who Hate Studying
Hate studying for the SAT? Stop grinding through material that doesn't move your score. Here's how to fix the specific skills holding you back.
How HIROSCORE Calculates Your Projected SAT Score
HIROSCORE's projected SAT score tells you what your current skill set is worth before test day. Here's how it's calculated and why it's more useful than a practice test score.
The HIROSCORE Methodology
Most SAT prep covers material. HIROSCORE finds gaps. Here's the methodology behind why students who've been grinding for months start moving again.
SAT Reading Comprehension: Central Ideas and Details
Central Ideas and Details make up roughly 14 of the 54 Reading and Writing questions on the SAT. Here's what the questions look like, where students lose points, and how to fix it.
SAT Command of Evidence Questions
Two types, one skill: match the evidence to the claim exactly. Here's how to work through textual and quantitative command of evidence questions without picking the answer that just sounds right.
How to Make Inferences on the Digital SAT
The correct answer must be proven by the passage — not just plausible. Here's how to spot the three wrong-answer patterns and find the sentence that settles every inference question.
SAT Command of Evidence — Quantitative Questions
SAT Reading and Writing includes Command of Evidence — Quantitative questions with embedded charts and tables. Read the claim first, then go to the chart with a specific target.
SAT Words in Context Questions
Words in Context questions don't test your vocabulary — they test how well you read a word in its specific sentence. Here's the four-step approach that eliminates the dictionary trap.
SAT Text Structure and Purpose Questions
Text structure questions ask how a passage is organized. Purpose questions ask what a specific sentence is doing. Here's the strategy for both — and the trap that trips students up.
SAT Cross-Text Connection Questions
Cross-text questions are the only SAT question type with two passages. The answer is always about the relationship between the two authors — here's how to find it.
SAT Rhetorical Synthesis
Rhetorical Synthesis questions give you bullet-point notes and a stated writing goal. The move most students miss: read the goal before you read the notes.
SAT Transitions
Transition questions test whether you understand how two ideas relate. The move that works: name the relationship before you read a single answer choice.
SAT Boundaries
Boundaries questions test whether you can punctuate the break between ideas. The one test that solves almost every one: is each side a complete sentence?
SAT Form, Structure, and Sense
Form, Structure, and Sense questions test whether the parts of a sentence agree. The move that works: stop reading for meaning and check the structure.
SAT Linear Equations in One Variable
Linear equations in one variable are the most common math skill on the digital SAT. The whole skill is one move: isolate the variable, one balanced step at a time.
SAT Linear Equations in Two Variables
Two-variable linear equations test how two quantities move together. Read slope and intercept straight off the equation and most of these answer themselves.
SAT Linear Functions
A linear function is just a line written as f(x) = mx + b. Once you read f(x) as the output for a given input, these questions stop looking like a new topic.
SAT Systems of Two Linear Equations
A system is just two lines at once, and the solution is where they cross. Solve them three ways — substitution, elimination, graphing — and learn when there's one solution, none, or infinitely many.
SAT Linear Inequalities
Linear inequalities solve like linear equations, with one catch: flip the sign when you multiply or divide by a negative. Learn one-variable ranges, two-variable regions, and systems.
SAT Equivalent Expressions
Equivalent expressions ask you to rewrite, not solve. Learn the four moves — factoring, expanding, exponent rules, and canceling rational expressions — and when each one is what the question wants.
SAT Nonlinear Equations and Systems
Nonlinear equations are almost always quadratics. Learn when to factor, use the quadratic formula, or Desmos, read the discriminant for the number of solutions, and solve nonlinear systems.
SAT Nonlinear Functions
Nonlinear functions test what an equation tells you about its graph. Learn the three forms of a quadratic, exponential growth and decay, and how to match equation to graph fast.
SAT Ratios, Rates, and Proportions
Ratios, rates, and proportional relationships come down to two habits: setting up the proportion right and tracking your units. Learn the setup, unit cancellation, and the conversion trap to avoid.
SAT Percentages
SAT percentage questions come in three types: find the percent, apply a percent change, or work backward from a total. Learn to spot each one and handle the reverse-percent trap.
SAT One-Variable Data
SAT one-variable data questions test measures of center (mean, median, mode) and spread (range, standard deviation). Learn to read tables and dot plots, compare data sets, and handle the outlier trap.
SAT Two-Variable Data
SAT two-variable data questions test scatterplots and lines or curves of best fit. Learn to interpret slope and intercept in context, match linear, quadratic, and exponential models, and predict values.
SAT Probability and Conditional Probability
SAT probability questions come down to picking the right denominator. Learn to read two-way tables, spot the conditional phrasings that shrink your denominator, and solve these in one division.
SAT Inference and Study Design
SAT inference and study design questions are reading questions in math clothing. Two checks decide every answer: random selection sets who results apply to, random assignment sets whether you can claim cause.
SAT Area and Volume
SAT area and volume questions give you every formula on an on-screen reference sheet. Learn where points actually leak: unit conversion, working backward from a given value, and composite shapes.
SAT Lines, Angles, and Triangles
SAT lines, angles, and triangles questions test a small set of rules — parallel lines, angle sum, similar triangles — applied to figures that hide the obvious. Learn how to spot which rule applies.
SAT Right Triangles and Trigonometry
SAT right triangle and trigonometry questions run on three tools: the Pythagorean theorem, special right triangles, and basic trig ratios. Learn which tool each question setup calls for.
SAT Circles
SAT circle questions combine circumference, arc length, sector area, and the circle equation with one core idea: a central angle's fraction of 360 degrees controls everything else.
