Rebuilding Classroom Lab...need deployment recommendations

We have a 20 computer training classroom that has primarily had a static image of applications built on it. We are in the early stages of building out a new setup and want to have the ability to pick from a list of images to deploy/boot from based on what training they will be performing. Essentially we want to have 3-4 different images that would only have the applications installed that need to be there for that particular class. The real kicker is that management wants the guy that is in charge of scheduling the training and generally oversees the use of that room to be able to do the deployments (non-IT and not tech savvy at all).

We use MDT for our regular deployments and I am curious if there is something better to manage this type of scenario. I know I could capture 3 separate images that have everything installed and sysprepped and we can pick from there...but in the event that there is an issue with the deployment I know it will lead to last-minute super urgent calls.

TL;DR: We want to be able to boot a workstation and pick from a list of 3-4 images and have it boot up in that configuration until next boot.
