Defintion The RP Group定义了RP组.pptVIP

Calculation: Steps 1 and 2 Disaggregate the target population of students by gender, age, and ethnicity and calculate percentages for each group (e.g., 50% female, 50% male) Calculate the percentage of students within each group that received a particular service, placed into a course or level, or met the prerequisite skill level for a course * Disproportionate Impact| RP Group Conference | April 2013 Calculation: Steps 3 to 5 Identify the majority or reference group and use that group’s percentage as the benchmark To obtain the ratio, divide the percentages for each other student group (minority group) by that of the majority or reference group Highlight any group with a ratio of less than 0.80 or 80% = disproportionate impact * Disproportionate Impact| RP Group Conference | April 2013 Example: The 80 Percent Rule The majority ethnic group is White students 60% of White students accessed the service 60% would serve as the reference rate Divide minority group’s rate by 60% (reference rate) So, if 50% of Hispanic/Latino students accessed the service, divide 50 by 60 to obtain the ratio for Hispanic/Latino students (50 ÷ 60 = 83%). Since the ratio for Hispanic/Latino students is greater than 80%, there is no evidence of disproportionate impact for this group * Disproportionate Impact| RP Group Conference | April 2013 Sample Data Table: Orientation Ethnicity Fall 2010 First-Time Students Received Orientation Services Ratio African American 240 8% 120 50% 83% American Indian/ Alaskan Native 30 1% 12 40% 67% Asian 300 10% 144 48% 80% Filipino 120 4% 50 42% 70% Latino 930 31% 465 50% 83% Multi-Ethnicity 180 6% 104 58% 97% Pacific Islander 30 1% 15 50% 83% Other, non-white 120 4% 72 60% 100% White 1,050 35% 630 60% 100% Total/Overall 3,000 100% 1,612 54% -- * Disproportionate Impact| RP Group Conference | April 2013 Shaded group represents the reference group Bolded rows identify groups for which disproportionate impact has occurred Promising Strategies Approach
