Following objections from local governments, two separate criteria have been approved.
As of September 1, 2016, a 10th grade class can be opened if there are at least 12 students per class, or a total of 32 high school students in grades 10 to 12 in regional schools.
However, at least 18 students, or a total of 48 high school students in grades 10 to 12, are needed to open up a 10th grade class in the following regions: Adazi, Babites, Baldone, Carnikava, Iecava, Ikskile, Incukalns, Kekava, Lielvarde, Salaspils, Saulkrasti, Skriveri and Stopini.

In Latvia's largest cities, a 10th grade class can be opened if there are at least 22 students per class, or a total of 58 high school students in grades 10 to 12.
Got that? If not, it's extra math homework for you!
