School Report Card System with Configurable Grading Rules and Batch PDFs

The problem schools have at result time

Twice a year, private schools go through result season. Teachers hand in marks on paper or in a shared spreadsheet, a coordinator types them into another sheet, formulas break when someone inserts a column, and the office prints report cards from a Word mail merge that takes a weekend. Every school has its own rules: tests count for 20 percent, a student absent for an exam gets "AB" not zero, a pass needs 40 percent in English and Maths, positions are shared on ties. When a parent disputes a grade, nobody can explain how it was calculated.

What already exists and the gap

• eSkooly is a free cloud school management system with exams and results among many modules.
• Fedena is an established school ERP with examination and report card modules.
• openSIS is an open source student information system with gradebook features.

These systems do include results, but schools often find the grading configuration either too rigid or buried among dozens of modules, and generating hundreds of well-formatted report cards is slow or needs a custom template from the vendor. The gap is a focused results system where grading rules are explicit and testable, moderation is built in, and report generation scales to a whole school in minutes.

What you build

Roles: admin (setup and rules), teacher (marks entry for their subjects), coordinator (moderation and release), principal (analysis and sign-off).

Flow: set up the term and assessments, teachers enter marks and submit, the coordinator reviews outliers and locks, the system computes results using the school's rules, and the office generates report cards for a class or the whole school in one go.

The technically interesting part

A grading rules engine that schools can trust. Represent the rules as data: weighted aggregation, rounding mode, grade boundaries, absent and exempt handling, pass criteria per subject, tie handling for positions. Evaluate them in a pure function with no database access, so it is easy to test. Every computed figure should come with an explanation trace a coordinator can open ("Maths: test 18/20 at 20 percent plus final 61/80 at 80 percent equals 79.0, grade A"). Use property-based tests to check things like "raising any mark never lowers the total".

Batch document generation. Rendering 800 PDFs in a web request will time out. Put jobs on a queue, render with headless Chromium from an HTML template, merge per class, and report progress. Make jobs idempotent and resumable so a crash at card 500 continues rather than restarts. Measure throughput and memory.

How to evaluate it

• Rules correctness: encode the rules of at least 2 real schools and test against results they already calculated by hand; report matches and explain differences.
• Throughput: time to generate 1,000 report cards on a modest server, and peak memory. Show the effect of worker concurrency.
• Marks entry: 5 teachers enter marks for a class of 35; measure time and validation errors caught.
• Explainability: give a coordinator 10 disputed results and measure how many they can explain using the trace without help.

Suggested plan

1. Weeks 1 to 3: collect grading rules and old report cards from two schools.
2. Weeks 4 to 8: academic setup, marks entry and validation.
3. Weeks 9 to 12: rules engine as pure functions with thorough tests and traces.
4. Semester 2, weeks 1 to 4: moderation workflow and results analysis.
5. Weeks 5 to 9: template editor and batch PDF pipeline with benchmarks.
6. Weeks 10 to 14: run one real or replayed result season, evaluate, write up.

Path to a product

Your first customer is a small private school where you studied or where a relative teaches. Sell per student per year, which matches how schools budget. Schools switch systems at the start of an academic year, so time your pilot and sales for that window.

Scope warning

Do not build fees, transport, admissions, timetables or attendance modules. Do not build a full learning platform. Do not try to support every board's rules in version one; make the engine configurable and prove it with two schools.
