Longitudinal Analysis. Setting up your Data Mart for Cohort-Based Longitudinal Analysis. Christopher M. Johnson, PhD Director of Research & Development Pat Chakravarty, Research Analyst Renton Technical College

Overview Tracks students by cohorts Disaggregates students by demographics Developed with existing tools and a very small budget Rapid prototyping system Expand its features statewide 3/16/20102Chris Johnson & Michelle Andreas

Features Goals of Longitudinal Analysis – Pinpoint intervention areas – Identify trends Cohort definitions – Loose - any group you want to look at with given characteristics (example, students who visited the Math lab) – Strict - Forward looking study - a group of students with characteristics that start at some point together. – Really Strict. IPEDS definition - First time, Degree Seeking, Fall t o Fall, etc. (about 5 percent of Fall enrollment) – Retrospective - take a group and looking backwards, for example, 2010 graduates. 3/16/20103Chris Johnson & Michelle Andreas

The Reports Reports - Standard vs. Ad hoc Analysis – Result tables - Course Enrollment, Program (plus other cohorts), Student Profile - allow for quick analysis. – Program - by Core Courses (other possibilities, CIP, EPC, etc.) – Standard Look and Feel With training & support from Institutional Research May be too detailed, but trying to get people to do own drilldown and familiarize themselves Ad hocs are mainly cross tabs. 3/16/20104Chris Johnson & Michelle Andreas

Results 41% of Full-Time Employees Easy access expands culture of evidence Open door policy and faster response Important research questions from “fishing trips” Regular training on access and use Feedback loop between Research & Staff 3/16/20105Chris Johnson & Michelle Andreas
