They’re fundraisers. My now 11th grader had spring portraits every year she was in elementary school. When she was in kindergarten, I expressed surprise, that they were doing portraits a second time in the same school year, and my 6 year old said to me, “Mrs. Jones says they’re so that you can see how much we’ve grown and changed, like if we’ve lost teeth.” Guess who was missing both front teeth at the time?
