If you pass the Exit Exam in high school are you then automatically eligible to leave with a diploma in hand?

I’m curious about this since I’m going to be a Sophomore this year. And I know I can take the test, but does that mean I can leave high school then? I asked my mom and she said No. You need to have the credits before you can get your diploma and leave. And that the exam only tells you that you’re eligible to leave. If you don’t have credits you can’t leave. So…I’m wondering is this true. Or has this changed?
