re: How much monthly allowance does a student athlete receive?

From the Northwestern decision:

"The grant-in-aid for the players’ tuition, fees and books is not provided directly to them in the form of a stipend as is sometimes done with room and board. Because the Employer’s football team has a rule requiring its players to live on campus during their first two years, these players live in a dorm room and are provided a meal card, which allows them to buy food at the school cafeteria.
In contrast, the players who are upperclassmen can elect to live off campus, and scholarship players are provided a monthly stipend totaling between $1,200 and $1,600 to cover their living expenses. Under current NCAA regulations, the Employer is prohibited from offering its players additional compensation . . .
