Developing a Persistence Index

IUPUI Edition

Why A Persistence Index?

Traditional One-Year Retention and Six-Year Graduation Rates reflect progress of a small proportion of students

Why A Persistence Index?

Campuses differ as to the “persistence disposition” of students according to service mission

Fall 2005 Undergraduate, Degree-Seeking Enrollment by Semester Credit Load

· IUPUI ·

Why A Persistence Index?

Traditional measures not directly relevant to faculty and administrators within schools and programs Few fall semester, full-time FTIC students enter

directly into majors Students enter at varying points in time Many students change majors

· IUPUI ·

How The Persistence Index Works

Arrays ALL undergraduate, degree-seeking students according to factors related to persistence that reflect student input differences Credit Load Class Level Prior Academic Performance

Calculates persistence rate “within cell” Weights campus cells by university-wide

proportions

· IUPUI ·

The Control Factors

Prior analysis (CHAID) used to devise categories that maximize persistence rate differences

Prior academic performance FTIC: SAT or ACT Equiv – 900 or less; 910 to 1130; 1140+ Transfers: GPA of transfer courses – 2.87 or less; 2.88 to

3.66; 3.67 or higher

· IUPUI ·

Limitations

Control factors not perfect Validity and reliability issues Other important input difference factors not

accommodated (e.g., campus residence status)

Small cell problems Imputation fills cells based on overall school

rate relative to overall campus rate Can not drill down too far

School level may be as far as possible, unless multiple years used for big departments

· IUPUI ·

Uses

Finding pockets and patterns Filling in the void between first year

retention and six year graduation points Stimulating dialogue at the all levels

(campus, school and possibly programs)
