The document discusses two potential solutions for implementing a National Testing Service (NTS) exam: 1) a paper-based exam administered in an exam hall or 2) an online exam administered in an exam lab. The online exam is deemed the most feasible solution as it requires less staff and resources, has lower costs due to eliminating paper and exam proctoring fees, and allows for strict timing controls through an online timer. Technical skills would be needed to implement the online system, but it is ultimately more economical and feasible than the paper-based option.
