# Zeugnis-System - Architecture Documentation
|
|
|
|
## Overview
|
|
|
|
The Zeugnis (Certificate) System enables schools to generate official school certificates with grades, attendance data, and remarks. It extends the existing School-Service with comprehensive grade management and certificate generation workflows.
|

## Zeugnis Workflow (Role Chain)
|
|
|
|
The certificate workflow follows a strict approval chain from subject teachers to school principal:

## German Grading System
|
|
|
|
| Grade | Meaning | Points |
|
|
|-------|---------|--------|
|
|
| 1 | sehr gut (excellent) | 15-13 |
|
|
| 2 | gut (good) | 12-10 |
|
|
| 3 | befriedigend (satisfactory) | 9-7 |
|
|
| 4 | ausreichend (adequate) | 6-4 |
|
|
| 5 | mangelhaft (poor) | 3-1 |
|
|
| 6 | ungenuegend (inadequate) | 0 |
|
|
|
|
### Grade Calculation
|
|
|
|
```
|
|
Final Grade = (Written Weight * Written Avg) + (Oral Weight * Oral Avg)
|
|
|
|
Default weights:
|
|
- Written (Klassenarbeiten): 50%
|
|
- Oral (muendliche Note): 50%
|
|
|
|
Customizable per subject/student via UpdateGradeWeights endpoint.
|
|
```
|
|
|
|
## API Routes (School-Service)
|
|
|
|
### Grade Management
|
|
|
|
| Method | Endpoint | Description |
|
|
|--------|----------|-------------|
|
|
| GET | `/api/v1/school/grades/:classId` | Get class grades |
|
|
| GET | `/api/v1/school/grades/student/:studentId` | Get student grades |
|
|
| PUT | `/api/v1/school/grades/:studentId/:subjectId/oral` | Update oral grade |
|
|
| POST | `/api/v1/school/grades/calculate` | Calculate final grades |
|
|
| PUT | `/api/v1/school/grades/:studentId/:subjectId/lock` | Lock final grade |
|
|
|
|
### Statistics
|
|
|
|
| Method | Endpoint | Description |
|
|
|--------|----------|-------------|
|
|
| GET | `/api/v1/school/statistics/:classId` | Class statistics |
|
|
| GET | `/api/v1/school/statistics/:classId/subject/:subjectId` | Subject statistics |
|
|
| GET | `/api/v1/school/statistics/student/:studentId` | Student statistics |
|
|
| GET | `/api/v1/school/statistics/:classId/notenspiegel` | Grade distribution |
|
|
|
|
### Certificates
|
|
|
|
| Method | Endpoint | Description |
|
|
|--------|----------|-------------|
|
|
| GET | `/api/v1/school/certificates/templates` | List templates |
|
|
| GET | `/api/v1/school/certificates/class/:classId` | Class certificates |
|
|
| POST | `/api/v1/school/certificates/generate` | Generate single |

|
| POST | `/api/v1/school/certificates/generate-bulk` | Generate bulk |

| GET | `/api/v1/school/certificates/detail/:id/pdf` | Download PDF |
|
|
|
|
## Security Considerations
|
|
|
|
1. **RBAC Enforcement**: All certificate operations check user role permissions
|
|
2. **Tenant Isolation**: Teachers only see their own classes/students
|
|
3. **Audit Trail**: All grade changes and approvals logged
|
|
4. **Lock Mechanism**: Finalized certificates cannot be modified
|
|
5. **Workflow Enforcement**: Cannot skip approval steps
