Schild Web Klassenbuchmodul

Online Class Book for German Schools – Analysis, UX & Launch

SchILD Web needed a modern class-book that works just as smoothly on a headmaster’s laptop as on a teacher’s phone. We delivered a web app that records grades, attendance and feedback in a few clicks. Clear navigation, traffic-light status colours and a responsive data grid make Excel sheets obsolete. In pilot grammar schools, final grade entry time dropped by 35 % and report errors were cut in half.

Analysis & Briefing

Teachers spent up to 15 minutes per class in the legacy desktop tool, and there was no mobile version. We ran workshops with 24 educators, mapped user stories and benchmarked rivals like WebUntis and EduPage. The main blockers: slow input and confusing grading scales.

We prioritised five key features: lightning search (< 0.2 s), subject filters, comment templates, attendance log and one-click PDF reports. Clear KPIs kept the roadmap tight at six sprints.

Design & Development

The UI had to be self-explanatory for both trainees and veteran teachers, meet WCAG 2.1 AA and stay snappy on ageing tablets while reflecting the SchILD visual brand.

We built a design system with Roboto, neutral greys and red-yellow-green accents. Front-end on React + TypeScript; row virtualisation lets 5 000+ records scroll lag-free. Modules (Timetable, Attendance, Performance) live as separate SPA routes; data comes via REST-API secured by JWT. CLS remains below 0.05, and a PWA wrapper enables offline use in Wi-Fi dead zones.

Optimisation & Launch

The platform had to be GDPR-compliant, integrate with school LDAP and survive peak loads of 1 600 concurrent sessions at term’s end, plus migrate legacy data from SchILD NRW.

GitLab-based CI/CD, JMeter load tests hit 2 200 RPS with p95 < 300 ms. Data is protected in transit (TLS 1.3) and at rest (AES-256), with automated S3-style backups. Go-live migrated 1.3 million records without downtime; week-one support saw zero critical tickets.
