It is not a recognized thing, but my daughter would get herself so tied in knots trying to excel in every class, I forced her to take a day on occasion in Jr. High. I was threatened by the school, and told the days would be counted as unexcused absence.
I told them that to stop me they would have to press charges, because I had my daughter’s welfare to worry about, and their only concern was numbers. The arguement was thrown at me that their solitary concern was education, I displayed my daughter’s rankings, and they shut up.
She was furious with me each time, but I spent the day discussing teachers, classes, classmates, and how she felt about each. It was visibly cleansing for her, and sending her to school the next day we both felt better.
I think one day per semester should be allowable, and schools refusing should be held accountable for child abuse.
