How to Schedule Volunteers for Events (Step-by-Step)

Whether you're running a 20-person church fundraiser or a 200-person nonprofit gala, volunteer scheduling follows the same core steps. The execution changes at scale — but the fundamentals don't.

Here's the complete process.

Step 1: Define What You Need

Before contacting a single volunteer, get clear on:

Roles needed — greeter, setup crew, registration, food service, cleanup
Headcount per role — minimum and maximum for each
Shift times — start and end for each role (they're often different)
Required skills — food handler cert, forklift license, bilingual, etc.
Priority order — if you can't fill every role, which ones are non-negotiable?

A complete role list before outreach prevents the chaos of discovering a gap 2 days before the event.

Step 2: Know Your Volunteer Pool

For each volunteer, you should know:

Contact info (email and phone)
Skills and certifications
General availability (weekends? weekdays? specific days?)
Past participation and reliability
Any preferences (prefers indoor work, can't lift heavy items)

If this information isn't already centralized, the first event is a good time to collect it. Use a simple form.

Step 3: Collect Availability for This Event

Even if you know general availability, always confirm for the specific event. People's schedules change.

Send an availability request 4-6 weeks before the event. Give a firm deadline (1-2 weeks out). Follow up once with anyone who hasn't responded.

ShiftSharks lets volunteers update their availability directly in the system — no email threads, no spreadsheet columns to update manually.

Step 4: Build the Schedule

With needs defined and availability collected, match people to roles:

Manually: Open your spreadsheet. Start with mandatory roles and your most reliable volunteers. Work down from there. This takes 2-6 hours for a medium-sized event.

With software: Input your roles and volunteer data. Let the algorithm suggest assignments based on skills, availability, and history. Review and adjust. This takes 15-30 minutes.

Either way, prioritize:

Mandatory roles (can't run the event without them)
Skill-match (put the right people in the right seats)
Load distribution (don't burn out your best volunteers on every shift)

Step 5: Review Before Publishing

Before sending assignments, sanity-check:

Every mandatory role is filled
No volunteer is double-booked
Skill requirements are met for critical roles
Shift times make sense (no one's scheduled to arrive before setup is done)
New volunteers are paired with experienced ones when possible

Step 6: Publish and Confirm

Send assignments to all volunteers with:

Their specific role and shift times
Location and any access instructions
Point of contact for day-of questions
What to do if they can't make it

Ask for confirmation. Don't assume silence means yes.

Step 7: Send Reminders

Two reminders:

72 hours out — "Reminder: you're scheduled for [role] on [date]"
24 hours out — "See you tomorrow! Here's what you need to know."

Include the cancellation/no-show contact info in both. The faster you know about a gap, the faster you can fill it.

Step 8: Track Attendance

After the event, record who showed, who was late, and who cancelled. This data makes your next schedule better automatically — and helps you identify volunteers worth recognizing.

The Time Investment

| Volunteers | Manual scheduling | With ShiftSharks | |-----------|------------------|-----------------| | 20 | 2-3 hours | 15 minutes | | 50 | 5-7 hours | 25 minutes | | 100+ | 10-15 hours | 45 minutes |

The time you save on scheduling goes back into event quality, volunteer relationships, and your sanity.
