Scholarships and grants are not typically reported on Form W-2. They are reported on Form 1098-T, with the excess of scholarship or grant funding over qualified tuition and fees treated as taxable income.
Form W-2 is used for reporting earned income. In the educational setting, reporting on Form W-2 would be confined to activities where the student expended personal effort to earn the funds: a federal work-study job, a graduate teaching or research assistantship, or similar employment.
