It goes on at all levels. High School, University, PPL, CPL, ATPL, other industries, IT certifications etc.
Where it doesn't happen is where the exam provider is diligent in creating new content, simulations and by using cheat detection algorithms. My university had a complex system used to detect cheating in all student submissions. It came back with a result next to your grade that had the names of the others that you cheated with along with a percentage figure on the probability that you co-ersed with that student.
IT exam providers such as Microsoft and Cisco use simulations where you need to configure the product live versus answering a multiple choice.
In the aviation world, it's left up to the employers really if CASA won't pull their finger out and get with the real world and create better materials.
A simulator will quickly sort out the pretenders from the real thing.
