Tuition refers to the fee charged by educational institutions for instruction and training. It is typically paid by students or their families and can vary widely depending on the type of institution, such as public or private schools, colleges, and universities. Tuition fees often cover the cost of classes, access to facilities, and sometimes additional resources like libraries and laboratories. In addition to tuition, students may also incur other costs, such as books, supplies, and housing. Many institutions offer financial aid options, including scholarships and grants, to help alleviate the burden of tuition costs for eligible students.
