School Bus Types Explained: 9 Models and How to Choose the Right One

It’s probably been a while since you last purchased a bus. Or maybe this is your first time. I can tell you that when you’re looking for a school district, a church, a private transportation company, or a skoolie conversion—knowing the different types of buses available can save you from overbuying, underbuying, or making a costly mistake.

I’ve seen people buy the wrong type of bus because they didn’t know the differences—and let’s just say returning a 40-foot diesel Type D isn’t as easy as returning a pair of shoes to Amazon.

This guide breaks down the nine common types of school buses, what each one is designed for, and how to match the right bus to your specific needs. So let’s roll.

1. Type A School Bus – The Compact Workhorse

• Chassis: Built on a van or light-duty truck chassis
• Capacity: Up to 30 passengers
• Use Case: Ideal for daycares, nonprofits, and tight city streets

Why choose it? If maneuverability matters more than seating capacity, a bus like this 2015 International Type A is your go-to. Many have lower floors for easier access and are great for urban environments.

2. Type B School Bus – The Rare Middle Ground

• Chassis: Stripped chassis with the entrance door forward of the front wheels
• Capacity: Typically 30–40 passengers
• Use Case: Less common, but sometimes used where mid-range seating and tight footprint are both needed

Note: You won’t find many of these on the used market. But we have a fine 2012 Bluebird Type B right here. Most buyers skip to Type A or C.

3. Type C School Bus – The Classic Yellow Bus

• Chassis: Built on a conventional truck chassis
• Capacity: 36–78 passengers
• Use Case: The standard choice for schools and many group transport needs

Why choose it? A bus like this 2011 International Type C is the most familiar bus for a reason—it balances size, capacity, and accessibility. Strong aftermarket support and parts availability.

4. Type D School Bus – The Transit Titan

• Chassis: Engine mounted in the rear (RE), front (FE), or under the floor
• Capacity: Up to 90 passengers
• Use Case: High-volume routes, long distances, or demanding transit needs

Why choose it? If you’re moving large groups every day and want maximum space and durability, a Type D bus like this 2009 Thomas Built Saf-T-Liner is your ideal choice. Just be aware: it’s not a fit for every road or parking lot.

5. Mini School Bus – Big Utility, Small Package

• Chassis: Often Type A, but a broad category
• Capacity: 10–24 passengers
• Use Case: Special education, senior transport, or community programs

Why choose it? Mini School Buses like this 2013 Chevy 3500 Thomas are nimble, often ADA-compliant, and less intimidating for new drivers.

6. Lift-Equipped Bus (ADA Compliant)

• Feature: Hydraulic wheelchair lift and wider aisles
• Capacity: Varies based on layout
• Use Case: Transporting passengers with mobility needs

Why choose it? Some states require these for specific services. A must-have for inclusivity. Here are some examples for you to check out.

7. MFSAB (Multi-Function School Activity Bus)

• Feature: No flashing lights or stop arms
• Capacity: Matches Type A–D, but used differently
• Use Case: After-school transport, field trips, or church activities

Why choose it? If you don’t need to make regular student pick-ups but still want a school bus frame, this 2009 Bluebird Vision MFSAB checks boxes.

8. Electric School Bus

• Chassis: Typically Type C or D platforms with EV drivetrain
• Range: 100–150 miles per charge
• Use Case: School districts and municipalities investing in green transport

Why choose it? Battery Electric buses like this Starcraft E-Transit Electric Van have lower fuel costs and fewer emissions. But shorter range, the lack of charging infrastructure, and up-front costs are real considerations.

9. Converted School Bus (Skoolie)

• Chassis: Usually retired Type C or D buses
• Use Case: DIY living spaces, mobile businesses, or adventure rigs

Why choose it? If you’re not afraid of a little work (okay, a lot), these can turn into incredible mobile homes like this 1990 Thomas Built Transit Liner Skoolie Conversion or business ventures. Just check your state’s registration laws first.
