Most training programs treat tests as the end of learning: teach, then check. A well-known line of research suggests the order matters less than people think, because the act of recalling something is itself a way of learning it.
That has a practical consequence for anyone who runs courses. Short, low-stakes practice tests are not just measurement. They are one of the cheaper ways to help people remember what they were taught.
What the study found
Roediger and Karpicke, writing in Psychological Science in 2006, compared students who took recall tests on material with students who spent the same time restudying it. Students who took recall tests remembered more on tests two days and one week later, although restudying did better on a test five minutes later.
Two parts of that finding matter for training design. First, the benefit showed up after a delay, which is when people actually need what they learned. Second, restudying looked better in the short term. Both students and trainers can be misled by that.
Why restudying feels better
Rereading notes or watching a module again feels productive. The material looks familiar, and familiarity feels like knowing.
Recall is harder. A learner who has to produce an answer from memory notices the gaps, which feels worse in the moment. According to the study, it is the approach that held up better over days.
This is why end-of-session feedback can mislead. If you test right after a lesson, the group that reread may look ahead. If you test a week later, the picture can change. Plan your evaluation for the delay that matters to your learners, not the one that is easiest to schedule.
Recall, not just recognition
The study used recall tests, where learners produced answers rather than picking them from a list. Many trainers take that as a reason to include some questions that ask people to write, list or explain, not only to choose.
Common practice is to mix formats:
- Short answer. “Name the three checks before you restart the line.”
- Ordering. Put the steps of a procedure in sequence.
- Scenario questions. A short case, then “What do you do next, and why?”
- Multiple choice. Useful for coverage, with distractors that reflect real mistakes.
Short answer questions take longer to mark. Rubric scoring with a person reviewing the results can keep that manageable on larger courses. Our automated grading service scores short answers against a rubric, with human review queues and an audit trail.
Design for low stakes
Practice tests help most when people are willing to get things wrong. If a quiz counts toward a grade or a performance record, learners start protecting their score instead of testing their memory.
- Keep scores private. Learners see their own results; managers see group trends at most.
- Allow retakes. Let people try again after reviewing what they missed.
- Give feedback fast. Show the correct answer and a one-line reason right after each item, or at the end of the quiz.
- Keep it short. Five to ten questions at a time is common practice.
- Say why. Tell learners that practice tests are part of how the course works, not a judgment of them.
Spread practice across the course
A single quiz at the end of a module helps. Quizzes spread across days or weeks are what many training teams use, as a matter of common practice, to keep material alive between sessions.
A simple pattern works for most courses. Give a short quiz at the start of each session on the last session’s material. Add a mixed review quiz each week that pulls from all earlier modules. Finish with a practice exam a few days before any final assessment, not on the same afternoon.
Mix older topics into newer quizzes. It is more effortful for learners, which is the point.
Keep practice and real items apart
If your course leads to a certification exam, keep the two item banks separate. Practice items should match the blueprint and the item style of the real exam, but they should never be copies of live items.
Separation matters for two reasons. It protects the security of the real exam, and it keeps the meaning of a certification score intact. For certification bodies that also train, it is part of managing impartiality, as our article on ISO/IEC 17024 impartiality explains.
Practice items still need to be good items. A poorly written question teaches the wrong lesson as effectively as a good one teaches the right one. Our item review checklist covers content, clarity, bias and accessibility checks for any item, practice or live.
Mistakes that weaken practice
A few habits undo much of the value of practice tests. Most are easy to fix once you see them.
- Answers on the same screen. If the answer is visible before the learner commits, there is no recall.
- The same ten questions every time. Learners memorize the quiz, not the material. Rotate items from a larger pool.
- Feedback that only says “wrong”. Show the correct answer and the reason, so the next attempt has something to work with.
- Quizzes only on easy recall. Include questions that ask people to apply a rule to a new case.
- Practice that counts. Once a score affects pay, grades or reviews, people stop risking mistakes.
- No time to retake. A retake the same day, after review, is where many learners close the gap.
None of these needs new software. They need someone to look at the quiz as a learner would.
Example: a three-day safety course
Example scenario. Say a training provider runs a three-day forklift and warehouse safety course, followed a week later by a certification exam that some employers require.
Before, the course ended each day with a review lecture, and the only test was the exam. Now, each morning opens with an eight-question recall quiz on the previous day: four short answers, two ordering items and two scenarios. Learners take it on their phones, see answers and reasons immediately, and can retake it at lunch. On day three, a mixed review quiz pulls items from all three days.
Between the course and the exam, learners get two short practice quizzes by email, on days two and five after the course. None of the practice items appear on the exam, which is built from a separate bank to the same blueprint. Instructors see only class-level results, which tell them which topics to spend more time on next run. This is a scenario, not a client account.
What to measure
You can check whether practice tests are helping without a research study. Compare outcomes on the same final assessment before and after the change, with the same delay between course and test. Look at item-level results to see which topics improve and which do not.
Treat the comparison with care. Groups differ, instructors differ and exams change. A difference in one cohort is a reason to keep watching, not proof. Item statistics from each window, such as how hard each item was and how well it separated stronger from weaker learners, will tell you more than a single pass rate.
What to do this week
- Pick one course and one module to start with.
- Write eight practice questions for that module, at least half of them recall rather than recognition.
- Add a one-line explanation to each answer.
- Schedule the quiz at the start of the next session, not the end of this one.
- Check that none of the questions appear on any live exam.
- Note the delay between your course and its final assessment, and plan evaluation around it.
Our online testing platform runs practice quizzes and live exams from separate banks on one account, with twelve item types and item statistics after every window. Our page for training providers shows how practice tests, final exams and credentials fit together in one program.
