This is how UIC makes their admissions decisions (from their website) - they don't list actual scores or GPA's, but at least you can see how everything factors in, percentage-wise. I am sure that all schools use some sort of formula like this, but it may not always be made public.
THE ADMISSIONS DECISION
The following elements of evaluative criteria are used by the Department of Physical Therapy Admissions Committee when reviewing applicants.
The Admissions Equation:
Total Selection Index Points = TSIP = 100 points
GRE Verbal and Quantitative sections (15%)
GRE Analytic Writing section (5%)
Cumulative GPA (15%)
Prerequisite GPA (25%)
Academic preparation (15%)
Additional factors (25%)
GRE Verbal and Quantitative (15%) will be based upon the sum of the scores in the verbal and quantitative sections.
GRE Analytic Writing (5%) will be based on the score of the GRE Writing Assessment.
Cumulative GPA (15%) will be computed based on the last 60 credit hours whether at the undergraduate or graduate level.
Prerequisite GPA (25%) will be computed by PTCAS based on grades earned in a common set of prerequisite courses that will likely include all of the UIC prerequisites except calculus.
Academic preparation (15%): will be based on
School attended: competitive vs. non-competitive
Course load taken/factors affecting course load (e.g. full time work)
Number of credit hours per term
Whether more than one science/math was taken per term
Additional science courses taken; caliber, type, grade, relevance, lab
Recentness of prerequisite science courses; update of old prerequisite science courses; work experience refreshing old sciences
Type and amount of prerequisites left to complete and plan for completion
Graduate course work taken and grades
Additional Factors (25%): will be based upon
Mitigating circumstances issue
Efforts since last application to program: additional course work, additional work/volunteer experience
Specific facts presented in personal statement and letters of recommendation
Work/volunteer experience
Cultural diversity
Other language fluency
Generic abilities
Reliability of the scoring system for Academic Preparation and Additional Factors and any potential for bias will be controlled. If the scores from the two reviewers differ by more than 40% of the weight of a category, a third reviewer will provide a score. The three scores will be averaged. If one of the criteria proves to be more or less predictive of success, its relative weight may be increased or decreased in future years.
