Assessment in education tells teachers what students know, what they still miss, and what they can do next. The three big types are diagnostic, formative, and summative, and each one answers a different question. Diagnostic checks look at starting point. Formative checks track learning during the lesson. Summative checks judge what students can show at the end. The biggest student mistake is thinking assessment only means a final test. That idea misses half the picture. Teachers also assess before a unit starts and during practice, not just after the chapter ends. A 20-question quiz on Friday and a two-minute class poll on Monday do different jobs, and both count as assessment. Educational psychology treats assessment as evidence, not punishment. Good teachers use that evidence to change pacing, reteach a 5-minute skill, move students into groups of 3 or 4, or raise the challenge for students who already mastered the material. That is why the question, “what are the types of assessment in education,” matters so much. It shapes what teachers notice, what students practice, and how progress gets measured across a 9-week unit or a full semester.
What Are The Main Types Of Assessment?
Diagnostic, formative, and summative assessment are the three core types students meet in educational psychology, and they each answer a different timing question: before, during, or after learning. A teacher might use a 10-item pretest on Monday, exit tickets on Wednesday, and a 50-point unit test on Friday.
The catch: Assessment does not start at the end of a chapter. It can begin on day 1, keep going for 6 weeks, and finish with a final score, which is why the common “test equals assessment” idea falls apart fast. That mistake matters because it hides the work teachers do while learning is still happening.
Formal and informal checks cut across those three types. A formal check uses a set format, like a district benchmark, a rubric, or a state exam such as SAT or AP. An informal check can be a hand raise, a quick oral question, or a 3-minute notebook scan. The first gives cleaner records. The second gives speed.
A smart teacher uses both. One tells you what the class can prove on paper. The other tells you what is happening in the room right now, which is often messier and more useful.
That messiness is not a flaw; it is the point. Real classrooms rarely move in straight lines, and a 1-minute check can catch a misunderstanding that a 100-point test would miss until too late.
Educational Psychology also uses these categories to study how learning changes over time, which is why the terms show up in college credit courses and teacher prep classes.
Students in a Introduction to Psychology course see the same logic in memory and feedback research: people learn better when they get information early, not after the grade posts.
How Does Diagnostic Assessment Help Teachers?
Diagnostic assessment happens before new instruction or at the start of a unit, and it tells teachers what students already know, where they have gaps, and which misconceptions may block new learning. A 15-minute pretest, a short interview, or a 5-problem probe can reveal a lot before day 2 even starts.
Reality check: Teachers do not use diagnostic results to assign a final grade. They use them to shape the next 3 to 10 lessons, adjust pacing, and decide who needs support, who needs review, and who is ready to move ahead. That makes diagnostic work practical, not ceremonial.
A reading teacher might discover that 8 of 24 students can decode words but stumble on vocabulary. A math teacher might find that 60% of the class can add fractions but forget common denominators. Those numbers change the plan fast. The teacher can group students, slow down, or add a mini-lesson before the unit gets harder.
This type of assessment also helps with readiness. A student who missed the last 2 weeks of algebra may need a different starting point than a student who mastered the same skill in summer school. Teachers who skip diagnostic checks often teach too fast for some students and too slow for others, and nobody wins that race.
Some classes use a quick benchmark on the first day, while others use a skills checklist, a concept map, or a short conference. The format matters less than the question it answers: what do students bring in with them?
How Does Formative Assessment Track Progress?
Formative assessment gives teachers ongoing feedback during learning, not after it ends, and that makes it the most useful tool for day-to-day adjustments. A 2023 lesson might use a 4-question quiz, a 2-minute exit ticket, and one round of peer feedback to show what students understand right now. Worth knowing: The point is not the grade; the point is the next move. If 12 students miss the same idea, the teacher reteaches it before the unit moves on.
- Exit tickets: 1 prompt in 3 minutes shows who got the lesson.
- Short quizzes: 5 to 10 items can flag weak spots fast.
- Cold questioning: 1 answer can reveal a whole class pattern.
- Draft feedback: comments on version 1 improve version 2.
- Observation: a teacher watching 6 tables can spot confusion early.
- Peer feedback: students compare work against a rubric before final submission.
A good formative check gives real-time evidence, not a final verdict. A student may miss question 4 on Monday and nail the same skill on Thursday after a 10-minute reteach. That shift tells the teacher the support worked, which is far more useful than a one-time score.
Some teachers overtrust quizzes and ignore discussion, but that is a weak habit. A paper score shows one slice of learning; student talk, drafts, and observation often show the rest.
Educational Psychology courses usually stress this point because feedback loops drive learning. The same idea shows up in Research Methods in Psychology, where evidence matters most when it changes a decision, not when it just sits in a file.

Summative assessment measures what students can show after instruction ends, so it acts like the finish-line check for mastery, achievement, or final performance. Common examples include a final exam, a 100-point unit test, a capstone project, or the course grade posted in a 16-week semester.
Bottom line: Summative results answer the question “What did the student learn by the end?” They do not tell the teacher how to fix tomorrow’s lesson, and that limit matters. A score of 88% on a final can show strong mastery, but it cannot show which mistake happened in week 2.
Standardized tests, end-of-unit essays, and final presentations all live here. A state exam may compare students across schools. A course project may compare students against a rubric with 4 performance levels. A final grade may blend homework, quizzes, labs, and tests into one mark that appears on the transcript.
That last piece creates a common confusion. Students often think the final grade tells the whole story, but it only summarizes the end result. Formative evidence shows the path. Summative evidence shows the destination.
Teachers still use summative data to make placement, promotion, and reporting decisions, especially in high school and college credit courses. The downside is simple: once the grade posts, the chance to improve that exact score usually disappears. That makes the pressure high, which is why steady practice during the unit matters so much.
How Do Formal And Informal Assessments Differ?
Formal and informal assessment differ in structure, scoring, and timing. Formal checks use a set format and clearer scoring rules, while informal checks happen in the flow of class and give faster feedback. Both can be useful in a 50-minute lesson, but they answer slightly different questions.
| Type | Formal Assessment | Informal Assessment | What It Tells Teachers |
|---|---|---|---|
| Example | Final exam, district benchmark | Class discussion, exit ticket | Mastery or quick understanding |
| Structure | Fixed rules, rubric, schedule | Flexible, spontaneous | Consistency vs. speed |
| Scoring | Points, grades, percent, 0-100 | Notes, check marks, observation | Comparable results or live clues |
| Timing | End of unit or term | Daily, even minute-by-minute | Final performance or in-the-moment progress |
| Use | Grades, placement, reporting | Reteach, regroup, adjust pace | Records vs. immediate action |
The formal side gives cleaner records. The informal side catches the stuff a test can miss, like hesitation, guessing, or a half-formed idea that disappears once the paper comes out.
Which Assessment Type Answers Which Question?
Each assessment type answers a different classroom question, and that is the whole trick. A teacher can get useful evidence in 5 minutes or 50 minutes, but the evidence has to match the decision.
- Diagnostic assessment asks: what did students know before this unit started?
- Formative assessment asks: what are students learning right now, during the lesson?
- Summative assessment asks: what did students master by the end of the 9-week or 16-week course?
- Formal assessment asks for scored evidence, like a benchmark, test, or final project.
- Informal assessment asks for quick signals, like observation, questioning, or a 2-minute exit slip.
- Educational psychology uses all 3 types to study growth, feedback, and memory over time.
- Teachers use the results to group students, reteach skills, and decide what comes next.
The most useful habit is matching the tool to the question. A pretest will not tell you how a student performs under final pressure, and a final exam will not tell you where the confusion started.
That difference matters in college credit classes, teacher prep work, and regular K-12 classrooms alike. The evidence changes the decision, and the decision changes the lesson.
Frequently Asked Questions about Educational Psychology
This helps you if you're a student, new teacher, or education major, and it doesn't help much if you only need a one-line definition for a class quiz. In educational psychology, the main types are diagnostic, formative, and summative, with formal and informal checks also used to track learning.
The main types of assessment in education are diagnostic, formative, and summative, plus formal and informal checks that teachers use across a unit, term, or full course. Diagnostic assessment comes first, formative happens during learning, and summative comes at the end.
You can read student progress wrong and give the wrong support. If you treat a pre-test like a final grade, or a final exam like daily practice, you miss what students know, what they still need, and where the gaps started.
Start by asking what you need to know: prior knowledge, current progress, or final mastery. That one choice points you to diagnostic, formative, or summative assessment, and it tells you whether to use a 5-minute exit ticket, a quiz, or a unit test.
Diagnostic assessment tells you what students already know before a lesson starts, so you can spot gaps in 1 class period instead of after 3 weeks. It can be a pre-test, a quick interview, or a short checklist, and it gives you baseline data, not a grade.
Most students think formative assessment means a quiz score, but it really means feedback during learning that helps you improve before the final grade. A teacher can use a draft, exit ticket, or 10-question check to see progress in the middle of a unit.
Most students cram for the test, but what works better is using formative checks over 2 to 4 weeks so the summative score reflects real learning. Summative assessment measures what you know at the end, like a final exam, end-of-unit test, or major project.
The biggest wrong assumption is that informal checks don't count, but a teacher's observation, class discussion, or 3-question exit slip can show progress faster than a long test. Formal assessment uses set rules and scoring, while informal assessment happens in real class time.
Formal assessments give a standard score, like a 20-item quiz or unit exam, while informal assessments show day-to-day understanding through questions, notes, and teacher observation. Together, they answer how do we know what students know types of assessment in real classrooms.
In psychology 120 educational psychology, you study how diagnostic, formative, and summative assessment show learning across time, not just on one test day. A psychology 120 educational psychology course often uses quizzes, reflections, and exams, and some versions can count as college credit, online course, or transferable credit through ACE NCCRS credit review.
Yes, you can study online and build knowledge of assessment types through an online course that covers diagnostic, formative, and summative testing. Some programs offer ACE NCCRS credit and transferable credit, so the course can count toward college credit at cooperating schools.
Final Thoughts on Educational Psychology
Assessment works best when you treat it like a map, not a verdict. Diagnostic checks show the starting point. Formative checks show the road bumps. Summative checks show the finish. Formal and informal checks sit inside all of that and give teachers different kinds of evidence, from a scored test to a quick answer across a desk. The common mistake is still the same one: people think a grade tells the whole story. It does not. A grade may show final performance, but it hides the earlier confusion, the mid-unit recovery, and the support that helped the student move forward. Educational psychology cares about that process because learning changes over time. Teachers who use the right type of assessment at the right moment make better calls on pacing, grouping, reteaching, and next steps. Students who understand the difference stop treating every check the same way, which saves time and cuts stress. If you want to read assessment questions with a sharper eye, start by asking one thing: is this check about before, during, or after learning? That one question clears up a lot fast.
