Dear Samuel,

After completion of your HSSLC i.e, Meghalaya Higher Secondary Examination, you need to complete a Bachelor (BA or BS) in Psychology degree, and then pursue Specialization at the postgraduate level, where you would get an MA or MSc in either Psychology, Social Work, or Counseling.
For further specialization and a good pay sale job, you need to go for the doctoral level as in PhD or MPhil.

However, you can still practise at small clinics after your BA or BS.

I hope this helps you!
