Managing template days

Templates support day-specific configurations:

1. Copy from another day — Duplicate an existing day's periods
2. Apply to all days — Copy one day's structure to all operating days
3. Generate standard schedule — Auto-create periods based on timing settings
4. Custom per day — Different structures for different days

Template validation

Before activating a template, the system validates:

Check	Requirement
✅ Has name	Template name is required
✅ Has operating days	At least one day selected
✅ Has days defined	Day structure for each operating day
✅ Has periods	At least one period per day
✅ All periods valid	No time conflicts within a day
✅ No gaps	No unexplained gaps between periods

---

Part 2: Periods

Periods are the time slots within a schedule where teaching and activities occur.

Period scope options

Scope	Description	Use case
All days	Same period on every day	Standard periods
Specific day	Period only on one day	Assembly on Fridays
Rotation	Different days in a cycle	A/B week rotations

Period duration presets

Duration	Use case
30 min	Primary school, short activities
35-40 min	Elementary school
45 min	Standard secondary period
50-55 min	Extended secondary period

Transition times

Configure buffer time between periods:

• Transition before — Time before the period starts (e.g., 3 min passing time)
• Transition after — Time after the period ends (e.g., 2 min cleanup)

Creating periods manually

1. Navigate to Scheduling → Schedules → [Schedule] → Periods
2. Click Add Period
3. Configure:
   • Period number and name
   • Start and end time (or duration)
   • Day scope (all days or specific)
   • Period type
   • Transition times (optional)
4. Save the period

Bulk period creation

For efficiency, create multiple periods at once:

1. Select Generate from Template to clone template periods
2. Or use Quick Generate with:
   • Start time (e.g., 8:00 AM)
   • Number of periods
   • Period duration
   • Break after periods (e.g., after periods 2, 5)
   • Lunch after period (e.g., after period 5)

Standard	8:00 AM	3:00 PM	6-7
Extended	7:30 AM	4:00 PM	8-9

Step 3: Scope

Define who the schedule applies to

• Whole school — All students and classes
• Grade level — Specific grade/year
• Stream — Academic track (Science, Arts, etc.)
• Class division — Single class section

Scope Priority

If multiple schedules apply, more specific scopes take precedence: Class > Stream > Grade > School

Step 4: Advanced Options

Configure constraints and rotation

Rotation settings:

• No rotation (same schedule daily)
• Weekly rotation
• Two-week (A/B week)
• Custom cycle

Constraints:

• Max consecutive periods for teachers
• Minimum break between classes
• Instructional minutes per week target

Step 5: Review

Verify and create

• Review all settings
• Check validation status
• Save as draft or submit for review

Validation checks:

• ✅ Required fields complete
• ✅ Timing is valid
• ✅ Scope is properly configured
• ✅ No date conflicts with existing schedules

Schedule review workflow

1. Author creates schedule in draft
2. Author submits for review
3. Reviewer (coordinator/admin) reviews schedule
4. Reviewer approves or requests revisions
5. Administrator publishes the approved schedule

Part 10: Schedule publication

Once validated and approved, publish the schedule to make it active.

Publication workflow

1. Validate — Run conflict check
2. Review — Address any warnings
3. Approve — Get necessary approvals
4. Publish — Activate the schedule
5. Notify — Inform stakeholders

Publishing a schedule

1. Open the approved schedule
2. Click Publish
3. Add publish notes (optional)
4. Confirm effective date
5. Click Confirm Publication

Post-publication

After publishing:

• Schedule becomes read-only
• Appears in teacher/student portals
• Previous active schedule is archived
• Audit trail is created

Making changes after publication

To modify a published schedule:

1. Create new version — Clone and edit
2. Emergency override — With admin approval
3. Temporary adjustment — For specific dates

Metric	Description
Total schedules	All schedules in system
Active schedules	Currently in use
Draft schedules	Work in progress
Published schedules	Made available
By type breakdown	Master, grade, stream, class
By status breakdown	Draft, active, archived

Teacher load statistics

Metric	Description
Periods per week	Teaching periods
Instructional minutes	Total teaching time
Periods per day	Daily breakdown
Subject distribution	Subjects taught
Class distribution	Classes assigned

Room utilization statistics

Metric	Description
Total slots	Available period-room combinations

---

Part 12: Rotation schedules

For schools using rotating timetables (A/B weeks, Day 1-6 cycles, etc.).

Rotation cycle types

Type	Description	Example
None	Same schedule every day	Monday always the same
Weekly	Different each week	Week A / Week B
Two-week	Alternating pattern	10-day cycle
Custom	User-defined cycle	Day 1 through Day 8

Setting up rotation

1. Choose rotation cycle in template or schedule
2. Set cycle length (number of days)
3. Define periods for each rotation day
4. System maps calendar dates to rotation days

Viewing rotation schedules

• Current rotation day shown in dashboard
• Week view shows rotation day labels
• Date picker shows which rotation day applies

Part 13: Best practices

Template design

Practice	Recommendation
Start simple	Begin with standard template, customize later
Standard durations	Use consistent period lengths
Adequate breaks	Include morning, lunch, afternoon breaks
Buffer time	Add transition minutes between periods
Naming convention	Use clear, descriptive names

Schedule creation

Practice	Recommendation
Use templates	Don't start from scratch
Plan hierarchy	Master → Grade → Class
Version control	Keep drafts, don't delete
Early validation	Check conflicts frequently
Stakeholder review	Get teacher input

Optimization

Practice	Recommendation
Pin critical assignments	Lock what must not change
Start with defaults	Use default constraints first
Allow adequate time	Don't set timeout too low
Compare solutions	Don't accept first result blindly
Iterate	Run multiple scenarios

Conflict resolution

Practice	Recommendation
Address errors first	Fix blocking issues
Document exceptions	Note why warnings are accepted
Verify resolution	Re-validate after changes
Prevent recurrence	Update constraints if needed

Part 15: Troubleshooting

Common issues

Persistent Conflicts

Conflicts won't resolve

Possible causes:

• Insufficient rooms for class sizes
• Not enough teachers for required subjects
• Overlapping scope schedules

Solutions:

1. Review room capacities and class sizes
2. Check teacher availability and loads
3. Verify schedule scope priorities
4. Consider adding resources (rooms, teachers)

Optimization Fails

Solver returns infeasible

Possible causes:

• Over-constrained problem
• Insufficient time slots
• Too many pinned assignments

Solutions:

1. Relax some soft constraints
2. Remove non-essential pinned assignments
3. Add more periods or operating days
4. Reduce hard constraint strictness

Slow Performance

Grid loads slowly

Possible causes:

• Large number of periods
• Many concurrent users
• Complex schedule structure

Solutions:

1. Use filters to reduce data
2. Avoid loading multiple views simultaneously
3. Clear browser cache
4. Try during off-peak hours

Changes Not Showing

Updates not reflected

Possible causes:

• Browser caching
• Concurrent edits
• Save not completed

Solutions:

1. Refresh the page
2. Check save confirmation
3. Verify you're on correct schedule
4. Check for concurrent edit warnings

Getting help

1. Check validation messages — The system explains what's wrong
2. Review conflict details — Click conflicts for resolution suggestions
3. Consult audit log — See who changed what and when
4. Contact support — For complex scheduling issues
