UT Austin Transfer Student Fall 2017- School of Social Work

My daughter is currently a Social Work major at Texas State University. Her current GPA is 3.8. She will have 40 hours of college credit at the end of Spring 2017 at Texas State (and I expect she will hang on pretty close to her 3.8 GPA). I see that the deadline for transfer applications is March 1st but when is the earliest she can submit her application to UT Austin? Does submitting an application before the March 1st deadline increase your chances of being accepted earlier? Or are transfer acceptances only sent out April - June? Any advice from students that have transferred into UT Austin School of Social Work would be appreciated. Thanks!
