It’s a good answer for keeping online education honest. It doesn’t need to be applied to all in-person schools, where teachers distribute spot checks across the course relatively evenly, but it makes perfect sense in conjunction with online testing. You only have to challenge one essay per student per term to catch cheaters with a near-perfect success rate. Assuming a 12 week course with 36 students, that’s qty.3-4 of teacher:student one on one meetings per week for the term; I think that’s doable. If you’ve oversold your teachers and have more than 36 students per, guess you’ll have to increase your labor expenses :D
