  6. What can we do with TLDS? Make informed decisions based on data • Assess Effectiveness of Policies and Programs • Identify impact/outcomes of services • Example: Unemployment or wage by education attained (i.e., Degree, Program) • Example: Determine success of program participants • Understand and align programs to workforce demand • Example: Adult education programs to develop computer skills when unemployed or incarcerated • Evaluate College and Career Readiness • Curriculum evaluation and reform • Example: Graduates require remediation in math despite taking Algebra II • Develop College and Career Indicators • Identify individual remediation needs and action plan • Example: Student declares desire to study engineering yet has only a basic proficiency in math • Improve Efficiency of Agency Operations • Cross agency information sharing • Example: Provide view of information for federal compliance reporting 6

  24. Imart data management framework • Data Imported ‘As-Is’ • Transformed to iMart Data Model • Assign Unique Identifier • Publish to Reporting Warehouse • Create Cubes for Analysis 24

  25. Unique Identifier (MPI) Overview • Identify individuals across multiple data domains using matching algorithms • Mask sensitive data to protect identity of individual • Assigns identifiers to uniquely identified individuals • Common elements: SSN, Name, and Birth Date • Not consistently available in all data sources • Can assign multiple identifiers • Flexible when new elements available for matching 25

  26. MPI Process Create Unique ID2 Source Data Apply Unique ID3 Identify New1 Identifies a new combination of data elements to enter matching process Steps through series of algorithms to determine if combination is unique and creates Unique ID Applies Unique ID to all individual records and suppresses identifiable data (Name, SSN/Fed EIN, and Street Address) in the reporting warehouse 26
