A Framework for Using CEDS for Analysis and Performance Management
Using the Framework • Step 1: Framing the Issue • The Question • The Audience • The Audience’s Focuses • The Approach • Step 2: Selecting the Right Metrics • Data Sources • Data Matching • Variables Used • Step 3: Constraining the Metrics • Output • Step 4: Data Use • Wages by Degree Level by Major • UAMS Study
The Question • What is the value of public higher education in the state of Arkansas?
The Audience • State Level Policy Makers • Administrators of Public Institutions of Higher Education • Students and Families
The Audience Focuses • Policy and Funding Issues • Program Planning and Staffing Issues • College Outcomes for Life

Data Matching Original Report New Version TrustEd Broker System SSN DOB First Name Last Name Uses multiple pieces of information about a person to determine if they match. Personally identifiable information is removed and replaced with a non-traceable id. • SSN from ADHE matched to SSN from ADWS
Identity Resolution (Wage Data) • ~55,000,000 records for 10 years, 2,938,718 unique SSNs, no DOBs, inconsistent naming standards. • 7,865 SSNs used by two or more people, for a total of 18,278 different individuals. Those would be combined incomes and treated as the same person if SSN was the primary key. • The same person has two or more SSNs (because of a typo/transposition) 13,373 times. There would be 13,373 additional (non-existent) people with separate incomes if SSN was the primary key.
