You do not need a 1098-T to claim the credit. But you do need to the school to be an "eligible institution".
To be eligible for the
tuition credits or tuition & fees deduction, the course must be taken at
"an eligible institution". The school should be able to tell you if
it is an eligible educational institution. In general, an eligible educational
institution is an accredited college, university, vocational school, or other
postsecondary educational institution, including accredited, public, nonprofit,
and proprietary (privately-owned, profit-making) postsecondary institutions.
Additionally, in order to be an eligible educational institution, the school
must be eligible to participate in a student aid program administered by the
Department of Education.
