Scandium outer configuration is 3d1 4s2 .it loses 1 electron from d orbital n 2 electrons from s orbital to form Sc3+ ion whose configuration is equivalent with argon which has a noble gas configuration. so it does not have many electrons in d orbital like manganese to show variable oxidation state.

Electronic configuration of scandium is
1s2 2s2 2p6 3s2 3p6 3d1 4s2 on the basis of
Incompletely filled 3d orbital in case of
scandium atoms in it's ground state (3d1)
It is considered as transition element.
