Data Sources and Impact Table Shells

In document Evaluation Analysis Plan (Page 123-128)

This section (i) summarizes the evaluation’s outcome data sources and (ii) illustrates how impact findings will be presented in evaluation reports in tables indicating data sources.

6.2.1 Summary of Data Sources

As discussed in Chapter Three, the net impact evaluation will draw on the following data sources:

 Administrative data from SSA and other agencies, including the Centers for Medicare &

Medicaid Services (CMS) and the Rehabilitation Services Administration (RSA);

 Stage 1 and Stage 2 surveys; and

 BOND Operations Data System (BODS) data, which includes data from random assignment, outreach, recruitment, intake, earnings data collection, and data exchange between BOND operational components and SSA.

The use of these sources to obtain the outcome measures in Exhibit 6-1 above is indicated in Appendix B.1. Specific examples appear in the table shells below.

6.2.2 Presentation of findings on earnings and employment

A full set of table shells for the impact analysis appears in Appendix B.2. To illustrate, Exhibits 6-3 and 6-4 provide table shells for Stage 1 and Stage 2 impacts on earnings and employment. As seen in these exhibits, SSA administrative records will allow for an examination of how impacts evolve over time. The three Stage 2 comparisons (T21 vs. C2, T22 vs. C2, and T22 vs. T21) will be shown together in the same table in order to minimize the total number of tables.
