For generations, grades and standardized tests have been the main way the system summarizes what a student has learned. They exist for understandable reasons: a teacher with 150 students needs a way to report progress, colleges need a way to compare applicants, and families want to know how their child is doing.
But a grade is a heavy compression. A semester of learning, effort, missed assignments, late work, participation and test performance all collapse into one letter. The problem is not that teachers grade badly. Most teachers know far more about each student than any letter can hold. The problem is what the letter is asked to carry.
What a grade actually measures
1. A mix of learning and compliance
A typical course grade blends what a student understands with how reliably they turned work in on time, followed the format and showed up. Those habits matter, but a student who has mastered the material and missed three homework deadlines can end up with the same grade as one who did every assignment and understood half of it.
đź’ˇ One number cannot tell you which part was learning and which part was logistics.
2. A moment, not a trajectory
Grades average performance across a term. A student who struggled in September and fully understood the material by December is often graded as if they half-understood it all along. The average records the struggle, not the learning.
đź’ˇ Mastery that arrives late still counts as mastery. An average does not see it.
3. Recall under time pressure
Many tests reward what a student can recall in a fixed window. Recall matters, but it is a narrow slice of ability. Cramming can produce a good score and little lasting understanding, and a student who understands deeply but works slowly can score below what they know.
đź’ˇ The ability to take a test is not the same as the ability to use what you learned.
What grades leave out
Some of the abilities that matter most are the hardest to grade:
✅ Problem-solving – Can you analyze an unfamiliar situation and find a way through? ✅ Creativity – Can you generate ideas and try them? ✅ Communication and collaboration – Can you explain your thinking and work with others? ✅ Adaptability – Can you learn something new when the situation changes? ✅ Application – Can you use what you know on a real problem?
Great teachers build projects and discussions to develop exactly these, and many assess them thoughtfully. The report card just has nowhere to put them.
Grades and risk-taking
When every assignment counts toward a permanent average, a mistake is costly. That quietly discourages the experimenting that real learning needs. Students learn to choose the safe answer over the interesting question, not because anyone told them to but because the incentive points that way.
đź’ˇ Learning needs room to be wrong on the way to being right.
A better measure: mastery, topic by topic
The alternative most educators already know is mastery-based assessment: instead of averaging a term into one letter, record whether a student can do each specific thing, and let them show it when they are ready.
That changes the questions:
- Not “what is your average?” but “which of these topics have you mastered?”
- Not “did you pass by the deadline?” but “can you show it now?”
- Not “how do you compare to the class?” but “what is within your reach next?”
It also changes what a student can show someone else: a record of specific, demonstrated skills rather than a GPA. That record is not a grade of record and not a qualification, and it does not need to be. It is evidence of what a person can do.
Where teachers fit
Mastery-based assessment is a lot of work to run by hand, which is one reason letter grades persist. DIY Degree is built to take some of that work off a teacher’s plate. Every topic in the app ends with a short check, and a learner’s mastery record shows which topics they have demonstrated, topic by topic. In the classroom pilot (built, not yet switched on in production), a teacher will be able to assign topics and see each student’s state on them: not started, in progress, mastered or stuck. There are no numeric scores in that view and no gradebook, and every export is marked “not a grade of record”, so it adds information without adding a second set of grades to keep. See what that looks like for teachers.
Conclusion: keep the mastery, lose the compression
Grades are a tool the system uses to summarize learning at scale, and they will not disappear overnight. But the most useful question about a learner is not their average. It is what they can do.
Measuring mastery topic by topic answers that question directly, and it gives students, families and teachers something a single letter never could: a clear picture of what has been learned and what comes next.
