Following the Metroplex Challenge, she competed in the WOGA Classic, where she tied for third in vault; Texas Prime where she took first on the beam and third on bars and AOGC Invitational where she tied for third all around. Due to a shoulder injury, Briley had to opt out of the Texas State Championships to be ready to compete in the Regional's via petition. Her focus on shoulder rehabilitation and conditioning paid off for her at the Regional's where she placed first in the All Around, Vault, Bars and Floor and qualified for the JO Nationals.
After Regionals and before the Junior Olympic Nationals, Briley tested for Elite status at the National Qualifier held at Texas Dreams in Coppell, TX. She successfully qualified as a Junior International Elite by compiling an overall score of 56.6 and finishing fourth overall in the Junior Division. This score qualified her for the US Classic in Houston and the Visa Nationals in Boston. In a joint decision with her coaches, Briley decided to pass on the Level 10 Junior Nationals and focus on the US Classic and Visa Nationals. She did well in her first Elite competition at the US Classic, placing eighth in the all-around and fourth on floor exercise. Briley's experience at the Visa Nationals was positive as well by finishing fifth on the beam and twelfth All Around, landing a spot on the Junior National Team. Briley concluded her 2008 season at the Massilia Gym Cup in France.
Briley started her 2009 season at three February meets beginning with the Metroplex Challenge, where she finished fifth in the all-around and third on floor exercise.

In early 2012, Briley made the decision with her coaches to return to Level 10 training in order to work on her increased course work in preparation for college. She is looking forward to perfecting updated routines with challenging skills while training hard in L10.
