That's an extremely over-optimistic design for tech student construction unless your center cherry-picks the top 10% of students + assesses them with an aptitude test before enrollment. I've sat through such a class (I needed other modules and it was a prerequisite I couldn't test out of) and had a lively (and somewhat acrimonious) debate with the college principal (ex Navy commander) about the critical flaws in the simple regulated PSU design we were supposed to build. It had a metal lever toggle switch as a mains switch but was in a plastic enclosure. It also couldn't deliver anywhere near the rated voltage/current because the transformer was underspecced and there wasn't enough headroom for regulation. I proposed grounding the switch body, increasing the reservoir cap (and I did a graphical analysis to approximate the required value) and derating the PSU. My objections were apparently not well received and most of the class were displaying extremely glazed expressions or were otherwise distracted. However the next session, it was "Thank you Ian" from the principal and there was a pile of supplementary sheets for the lab handout detailing the chainges and two parts bins with the bigger caps and solder-tag washers to fit the switch sitting next to them on the instructors bench.
If my class had been given your schematic to build, I estimate you'd have had about two of us succeed, which was about 10% of the class. That would have been me and the only other guy with hobby experience building circuits. Maybe something LM723 based could be a happy compromise?
