American River College Integrated Planning System Reports

2018 Disproportionate Impact for Biology Overall
A_B Rate Metric (F15-S18)

The following is intended to provide an overview of where disproportionate impact (DI) exists in the A-B Rates (% A,B grades) of different racial/ethnic groups within your planning unit. Greater detail can be found in the Department DI Detail Spreadsheets which are available for each of the course designators in your department (BIOL). These nine-tab spreadsheets show your DI data at the department and course level, disaggregated by race, gender, and gender within race. (To protect the identity of faculty, DI statistics are provided only for courses that have been taught by at least three faculty members during the three years we merge for these reports. An unrestricted report may be obtained if all of a planning unit’s faculty are agreeable, and doing so typically results in DI data being reported for additional courses beyond those shown in the restricted version of the reports.)

Please refer to ARC’s DI Interpretation Guide for assistance in understanding and differentiating between ARC’s two DI reports (the web-based report shown here and the Dept DI Detail Spreadsheet(s), linked above)

The Disproportionate Impact methodology shown here reflects the four different methodologies recommended by the State Chancellor's Office, including the most recent, the Percentage Point Gap Methodology with Margin of Error. Applied to the success rates of the courses your unit has offered over the last three years, the above table shows the following:

  • red     Groups with success rates showing Definite DI
  • lightred P     Groups with success rates showing Potential DI (rates within 3 points of the group’s DI threshold)
  • yellow     Groups with success rates that may possibly have DI, but for which too little data exists to be sure (<10)
  • green     Groups with success rates showing No Measurable DI
