Understanding Your Student's Progress
A student's Progress tab has three sub-tabs: Reports, Classwork, and Skills. Each answers a different question, from "how's the week going, in plain language" to "exactly which skill needs work." Here's what each one shows, report by report, and, if you want to look under the hood, how the numbers behind them are actually measured.

Reports: the weekly story
Reports is the sub-tab most parents live in. It opens with a written summary of the week and then stacks a series of report cards underneath: charts, rankings, and callouts that each look at your student's work from a different angle. Some of them only appear once there's something to show (a misconception has to recur before there's a misconceptions report, for example), so don't worry if your view is shorter than the list below.
The reports, one by one
This Week's Story
This Week's Story is a plain-English narrative of what happened for that student over the most recent week of work. It isn't a template; it's written fresh whenever there's new activity to describe, and re-written at least daily so it never describes a stale window. Underneath it, Highlights calls out the most notable one or two facts from that stretch, and Next Steps suggests what would help most right now.
What Primer is noticing
This card breaks observations into Strengths and Growth Areas, plus short Recent progress and Engagement notes. These come from your student's actual answers, not from a survey. This is where you'll usually find the most specific, actionable detail, like exactly which kind of question your student tends to miss.
The numbers at a glance
Three stat tiles give a quick numeric snapshot: Lessons Completed, Skills Tracked, and Units Mastered (curriculum units your student has demonstrated mastery on, not just finished).
Mastery charts
The Mastery by Skill line chart plots each tracked skill week by week, so you can see which skills are climbing and which are stuck. A toggle switches it to Overall, a single averaged line for the big-picture trend. Once your student is working in more than one subject, a separate Mastery by Subject chart shows one line per subject (Math, ELA, and so on). Every point on these charts is a weekly snapshot of the mastery number explained below.
Activity charts
The Activity heatmap covers the last 12 weeks (one square per day, darker squares meaning more lessons that day) with a count of active days beside it. Next to it, Lessons per Week is a simple bar chart of output over time. Together they answer "how consistently is my student showing up?" rather than "how well is it going?"
Skills by Mastery and the Skill Universe
Skills by Mastery ranks tracked skills from weakest to strongest (up to fifteen of them), so the skills that need attention float to the top. Each skill has a checkbox: tick a few and the charts and celebrations below filter to just those skills, which is handy when you only want to watch, say, two math skills. The Skill Universe re-draws the same data as a map: every skill is a planet sized by mastery, and the small moons orbiting it are individual exit tickets (sized by question count, colored by score).
Recurring Misconceptions
When your student keeps making the same kind of mistake (not just missing questions, but missing them the same way) it shows up here with a count of how often it's recurred. Click a row to see how Primer explains and corrects that specific misconception, in the same words your student saw.
Help Requested
This card tracks how often your student asked the built-in Coach for help, split by where it happened (lesson, practice, or exit ticket), trended per week, and ranked by which skills prompt the most asks. You can expand recent asks to read the exact exchange: what your student asked and how the Coach replied. Higher numbers aren't bad; they usually mean your student is engaging instead of guessing.
Celebrations
Milestones worth sharing at the dinner table: curriculum units your student completed (with a running "4 of 12 units" style count for the skill), skill milestones, and accommodations lifted: supports Primer was providing that your student no longer needs, which is its own kind of progress. Primer deliberately waits for real evidence before celebrating; see how progress is measured for the bar a skill has to clear.
Handwriting
A Handwriting panel sits at the bottom of Reports. Until a handwriting page has been finished it just tells you what would make it fill in; after that, it shows a letter-by-letter grid (warmer squares where a letter is going well, grey where it hasn't been practiced yet) plus callouts for reversed letters. Handwriting is measured from the written page itself (on an iPad, finishing the page with a pencil measures every letter), not from quiz questions, which is why handwriting skills show "On the page" instead of a percentage in the Skills tab.
Classwork: lesson by lesson
Classwork is the ledger view: four stat tiles (Completed, Total Lessons, Avg Score, Questions) followed by every lesson and worksheet, each with its own status and score. A lesson that's done shows a completion date and how many questions were answered correctly (for example, "5/6 correct"); one still underway shows In progress. Worksheets appear in the same list with a purple Worksheet tag, so you can see practice material alongside the lessons that generated it.
Skills: mastery, confidence, and exit tickets
Skills breaks progress down to the individual skill level, grouped by subject (for example, ELA and Math), with a mastery percentage next to most of them in the sidebar. (Handwriting skills show "On the page" instead, since they aren't scored from questions.) Clicking a skill opens a detail panel headlined by three numbers:
- Mastery: how well the student has demonstrated this specific skill, weighted toward their most recent work. This is the number the mastery charts in Reports are built from; how it's measured is explained below.
- Confidence: how much evidence sits behind the Mastery number; how sure Primer is about it, not how sure your student felt. It climbs as your student answers more questions on the skill with consistent results, so a skill with only a handful of questions behind it shows lower confidence than one with many, even at identical scores. What counts is the number of questions, not the number of tickets: two long exit tickets can carry more evidence than ten short ones. Low confidence just means "early days; don't over-read the mastery number yet."
- Exit Tickets: how many Exit Tickets (the final, scored check at the end of a lesson; see Inside a Lesson: A Full Walkthrough) have touched this skill.
Below the three numbers, the panel goes deeper: a Mastery Trajectory chart for that one skill, an Exit Ticket History listing every ticket with its date, score, and question count, and Recent Questions, the actual questions your student was asked, with how each was scored. If you ever want to check the numbers against the raw evidence, this is the place.
If a skill shows 0% across the board and "No exit tickets or questions recorded for this skill yet," that's not a red flag by itself; it usually just means your student hasn't reached a lesson that exercises that skill yet.
How Primer measures progress
You don't need any of this section to use the Progress tab, but if you've wondered what's actually behind the percentages, here it is in plain language.
The exit ticket is the measuring stick
Primer doesn't grade your student on practice, hints, or how long a lesson took. The measurement moment is the exit ticket: the short, scored check at the end of every lesson. Each ticket produces a score (the share of its academic questions answered correctly; reflection questions like "how did that feel?" are never counted), and that score is what moves the numbers.
Mastery is a moving average, weighted toward recent work
Mastery is not a lifetime average of every question ever answered. It's what statisticians call an exponential moving average: every time an exit ticket comes in, the skill's mastery moves toward that ticket's score, with the new ticket counting for roughly 40% of the updated number and everything that came before it counting for the other 60%. Older results never disappear; they just fade in influence with each new ticket.
In practice this means three things:
- Recent work counts most. If your student struggled with fractions in September but has been landing them all November, mastery reflects November: the chart will show the climb rather than punishing the past.
- One bad day can't crater a skill. A single rough ticket pulls mastery down by less than half of the gap, so an off morning shows up as a dip, not a collapse.
- One great day can't max it out either. A perfect first ticket lands a skill in the low 80s, not at 100%. Staying high takes consistently strong tickets, which is exactly what mastery is supposed to certify.
A brand-new skill starts from a neutral benefit-of-the-doubt baseline (70%) rather than zero, so the very first ticket lands somewhere honest instead of making the first lesson look like a rescue mission. And when the evidence says your student already knows the material (they skipped the practice, aced the exit ticket, and rated it easy) Primer weights that ticket far more heavily so mastery jumps at once instead of inching up over several lessons a student never needed.
Confidence is about evidence, not feelings
Confidence measures how much trust the Mastery number has earned. Under the hood it's a statistical estimate that considers both how many questions your student has answered on the skill and how consistent the results have been: five questions can never produce the same confidence as fifty, and scores that swing (100%, then 50%, then 100%) keep confidence lower than three steady tickets would. And it's deliberately conservative: even a long run of strong tickets leaves a sliver of doubt rather than claiming certainty, since any measurement of a growing kid has some noise in it.
When Primer says "mastered"
Celebration-worthy claims are deliberately conservative. Before Primer celebrates mastery of a skill, four things have to line up: high mastery on that skill (roughly 85%+), solid confidence in it (roughly 75%+, which usually takes about three consistent exit tickets), at least three exit tickets recorded against that skill, and at least three completed lessons for your student overall. One perfect quiz can't mint a "Mastered" badge. That's a feature, not a bug.
If your student is just getting started
With only a lesson or two completed, don't read too much into any single number yet. Primer treats the first few lessons for any student as an early-progress check-in rather than a real measurement, and Reports will usually say so directly. The most useful next step at that stage is almost always just completing another short lesson, so there's enough activity for real patterns to show.
If a report ever raises something that concerns you, or you want more context than the numbers give, that's exactly what emailing your student's teacher is for.
