The Spousal Equivalent has his master's degree in "Instructional Technology". In other words, different ways to teach things. There's no "one-size-fits-all" in teaching/learning.
By that Texas measure, I started 1st Grade in Cupertino California at age 5.8. California now has a similar September 1 starting date with options. Thus was 4.8 when I started kindergarten and throughout following grades, was always the youngest person in every grade, a significant disadvantage because I was also the smallest male. At that time individual districts decided when kids would start and Cupertino was one of the few earliest. There were neighborhood friends a bit older than me that were in the grade below mine. I, an oldest child without others to talk to, had social and speech problems so didn't catch up with others mentally until the 4th Grade, and by the 6th Grade was put in with advanced students.There's no kindergarten requirement in Texas. The year a child becomes age 6 by September 1st, is the year they are required to start school, which, at that age, would generally be 1st grade, and continuing education is mandatory from there on until graduation, or age 19, whichever comes first. My daughter left Texas before age 19 without completing school, and sometime after that got a GED.
When I started Junior high school(middle sch.) at age 12 there was a guy in our homeroom named Rico Sanchez. He was 16, not excelling academically, but he was a fantastic artist / cartoonist. He drew all sorts of "Rat Fink" automotive cartoons of the day, plus anything else really.When I was in High school we had two guys in our graduating class that were 20 years old because they had had to repeat a couple of grades which was the practice back then. I think the way it worked backed then was after being held back twice you just got socially promoted after that. That way you didn't have 35 year old High School students. They were both still dumber than a bag of hammers but I suppose they would have been worse if they had been socially promoted all along.
