First-Year Conversion Rate
AlcoholEdu for College is administered annually to incoming first-year classes beginning in mid-August prior to students arriving on campus. Students complete a follow-up survey approximately 6-8 weeks after the start of Fall quarter to measure their drinking behavior after being on campus. The graphic below shows the changes in quantity/level of drinking from the pre-arrival survey to the level of drinking approximately 6-8 weeks after arriving on campus. All answers are according to behavior within the past 2 weeks of taking each survey.
This diagram depicts our first-year “conversion rate” which identifies the change in drinking level from pre-arrival to mid-fall quarter.
You will find data from the classes arriving on campus in Fall 2016, 2017, and 2018.
- Historically, 30-35% of incoming first-year Northwestern students identify as Abstainers prior to starting the academic year.
- In 2016-2017, our Heavy Episodic and Problematic conversion rates were 2.5 times greater than that of the national conversion in these categories.
- Northwestern consistently has a lower percentage of Abstainers and a higher percentage of Nondrinkers coming to campus to that of the national average.
