She told the board she had spent "too much time in prison to come back" and had "bigger things to do".
When she last appeared before the board in January she held a high security classification.
That status had been lowered but then changed again when she was found with homebrew.
She admitted to the board that she had "still made some silly decisions" but had taken responsibility and worked hard on compliance since.
While her behaviour had improved in the past month it had been noted she "likes to push the boundaries with certain staff", Coleman said.
However, the board found Pritchard-Davis had engaged well in programmes, was "excited about her future" and had made good decisions about her release plan.
"She has done well in prison for a young woman and is demonstrating clear signs of maturity and positive thinking," Coleman said.
The 21-year-old will be released on August 3 and will be subject to standard and special release conditions.
Special conditions include:
• Not to possess, use, or consume alcohol, controlled drugs or psychoactive substances except controlled drugs prescribed by a health professional.
• To attend an alcohol and drug assessment, and complete any treatment directed by a Probation Officer.
