Wordless Wednesday - School Uniforms 1940s

Circa early 1940s

I would love to know what these young women are doing dressed in overalls. Fourth from the top right is my aunt Beverly Shepard Agard. In 1940 her family lived in Ithaca, but during the war the family moved out to Dryden, NY where her father tried his hand at farming.  Are these young women in training to be the U.S. version of "Land Girls?"
