Should I just graduate with a B.S in criminal justice and a minor or another one ?

Hello, I am currently attending utrgv and I been considering taking a second minor to be able to qualify for a teach grant to get a masters in special education. Currently I am set to graduate in Fall 2018 with a B.S in criminal justice with a minor in sociology. Thus, to qualify for the grad course I would need to atleast have a minor in Special Education which is a semester and a half more. Neverthless, I am confused with how much the teach grant would cover the my whole masters degree due to it being close to $13,750 for 10 months. To be honest, I am only getting a b.s in criminal justice because I want to be a teacher and work for the school district but getting a masters in criminal justice would costly. Can anybody help me solve my dilemma please.

VERY IMPORTANT:

  1. a criminal justice major will NOT qualify you to teach. It’s a major that leads to working in department of corrections, aw enforcement…
  2. the master’s you found is for CERTIFIED teachers.

If you want to teach, you need to switch to a major from the College of Education and P16 integrated studies, and choose one of the three integrated concentrations in Elementary education (bilingual education, special education, ESL).
Switching now will likely add two semesters to your degree but all your Gen Ed courses and a few basic courses will count onyoure not too far off.
Do not graduate as you’d lose your access to federal financial aid - stay in college and switch courses for this summer session + Fall.
