Yeah, picking up undergrads (or even grad students) from the CS department is not a surefire way to end up code that follows best practices, is well maintained/documented, etc. and I'd probably argue if your team leader doesn't have that experience, you're more likely to end up with something that doesn't follow great practices (especially with regards to any sort of test suite).
