TExES Core Subjects EC-6 (391) Exam Study Guide

The TExES Core Subjects EC-6 (391) is a computer-administered test (CAT) built from five separate Subject Exams that are typically taken together in one appointment. Before you schedule a date, lock in these logistics.

• 210 total selected-response questions spread across the five subject exams.
• 300 minutes (5 hours) of total appointment time, which includes a 15-minute CAT tutorial and compliance agreement before the questions begin.
• $116 to register for the full 5-Subject Exam as one appointment, or $58 per Subject Exam if you choose to test on individual subjects separately.
• Additional fees beyond the base registration fee may apply depending on how and when you register, so confirm current charges before paying.
• You must pass every one of the 5 Subject Exams — Texas reports the overall result as Passed or Not Passed, since there is no single combined passing score for the whole test.

Because the pass rule is per-subject, a strong score on Mathematics cannot offset a weak score on Science. Plan your study time so every subject clears the bar on its own.

Core Subjects EC-6 is really five mini-exams delivered back to back. Knowing how long you have for each one lets you pace yourself instead of discovering the clock problem mid-test.

• English Language Arts and Reading — 45 selected-response questions in 70 minutes.
• Mathematics — 40 selected-response questions in 70 minutes.
• Social Studies — 40 selected-response questions in 50 minutes.
• Science — 45 selected-response questions in 55 minutes.
• Fine Arts, Health and Physical Education — 40 selected-response questions in 35 minutes.

Notice that Social Studies, Science, and Fine Arts/Health/PE give you noticeably less time per question than English Language Arts and Reading or Mathematics. If you tend to overthink multiple-choice items, those tighter subject exams are where a timing strategy — read once, eliminate obviously wrong answers, commit — pays off most. Rotate your review sessions so every subject gets dedicated time rather than letting whichever subject you like best eat the calendar.

Your score report will not show a raw count of correct answers. Instead, each Subject Exam is converted to a scaled score, and you need to reach 240 on that scale on each of the five exams to pass.

A scaled score exists so that scores are comparable across different test forms — since not every version of the exam is exactly the same difficulty, the raw number of questions you get right is adjusted onto a common scale before it is reported. That means two testers who answered a different number of raw items correctly on two different test forms could both land at exactly 240, because the scaling accounts for each form's difficulty.

• Passing threshold: 240 scaled score, per subject exam.
• You must clear 240 on all five subject exams — clearing four out of five does not pass the overall test.
• There is no overall combined scaled score; each subject stands alone, and the final report is simply Passed or Not Passed.

Practically, this means you cannot average out a rough subject with a strong one. Treat each of the five subject exams as its own pass/fail checkpoint when you build a study plan.

Core Subjects EC-6 is delivered as a computer-administered test (CAT), not a paper-and-pencil exam. Before your 210 scored questions begin, you'll spend part of your appointment on a required 15-minute CAT tutorial and compliance agreement, which walks through the on-screen tools (flagging items, moving between questions within a subject, submitting answers) and confirms you understand testing rules.

• Format: computer-administered test (CAT) — all five subject exams are selected-response (multiple-choice style) items delivered on screen.
• Tutorial and compliance agreement: 15 minutes, part of your total appointment time, not scored.
• Total appointment window: 300 minutes, covering the tutorial plus all five timed subject exams.

Because the tutorial time is baked into your 5-hour appointment, practicing on a computer-based interface beforehand — clicking through choices, using an on-screen flag/review feature, navigating between items — means you spend that tutorial time confirming what you already know rather than learning the interface for the first time under pressure.

Since each of the five subject exams must independently clear a 240 scaled score, the most effective prep plan treats them as five separate mini-courses rather than one undifferentiated study block.

• Diagnose first. Take a full-length practice test before you study anything, and score it by subject, not just overall — that tells you which of the five exams needs the most hours.
• Weight your calendar by weakness, not by preference. It's tempting to spend extra time reviewing the subject you enjoy; discipline your schedule toward the subjects where your diagnostic was weakest instead.
• Use spaced repetition for content-heavy subjects like Social Studies and Science, where recall of discrete facts and concepts matters more than for skills-based subjects.
• Practice under timed conditions for the shorter subject exams especially, since a tight time allotment rewards decisive answering over lengthy deliberation.
• Retake practice questions you missed a few days later rather than only reviewing the correct answer once — spaced retrieval is one of the best-supported study techniques for durable recall.

A study plan built around five separate checkpoints, each scored to its own passing standard, is fundamentally different from studying for one combined exam — treat it that way.

The single best way to walk into a 300-minute, five-subject appointment with confidence is to have already sat through a full-length practice test under the same conditions: no notes, a timer running, and all five subjects completed in one sitting.

• Rehearse the full length. Sitting through a complete practice exam builds the mental stamina needed for a 5-hour appointment — fatigue late in a long test is a real factor, not just a content-knowledge one.
• Practice the transition between subjects. Moving from Mathematics into Social Studies mid-appointment requires a mental reset; rehearsing that switch in practice reduces the jolt on test day.
• Review every missed practice question for the reason, not just the right answer. Understanding why a distractor was wrong generalizes better to new questions than memorizing one correct answer.
• Simulate the computer interface. Practicing with an on-screen, timed, multiple-choice format mirrors the actual CAT delivery closer than paper flashcards alone.
• Arrive rested and plan for the full 300-minute window — pace yourself knowing the appointment includes the tutorial time as well as all five timed subject exams.

A practice test is not just a score prediction — it's a rehearsal for the exact appointment structure you'll face.
