How did Summer Vacation got to be?

Summer Vacation started in the late 1800s in the urban schools America, and that was when Summer Vacation started. At that time, school used to be all-year round, and students only showed up at school for half of the year! Also, school was not mandatory. 

The reformers though about it, and it may have been because of too much school, and it was resulted that test scores in the late June was better than at the start of September. And, it's believed by countries that student has to take a break from school because too much school can result in depression, nervous disorder, insanity, and separation anxiety from parents. 

The reformers started giving breaks to student, and they chose Summer. Reason being, the school facilities were expensive, so they could not be opened all year, and schools with lousy ventilation could lead to heat waves, and the community members were afraid that the hot weather would lead to disease. 

In conclusion, Summer Vacation started because of the urban schools in the USA in the 1800s had school for 365 days or 366 days of school, and students did not appear in class for half of the year as over studying may lead to serious medical conditions. Despite that, Summer Vacation started. From then on in America, students only studied for about 250 days, and the attendance of students increased. 

Thank you!
