This paper focuses on the data ramification of the Workforce Investment Act (WIA) and the Carl D. Perkins Vocational and Technical Education Act of 1998. Section 1 provides an outline of the role of these postsecondary institutions under WIA: members of the State and local boards; one-stop operators; one-stop partners; and eligible service providers. Section 2 discusses accountability provisions of WIA, the Adult Education and Family Literacy Act (AEFLA), and the Perkins Act. It addresses Title I of WIA which requires states and local areas to establish performance measures (core indicators of performance, customer satisfaction indicators of performance, levels of performance) and mandating sanctions for failure to meet state and local performance measures, national comparability of performance data, reports, and state evaluations. It considers two required AEFLA performance measures: indicators of performance and levels of performance. These requirements of the Perkins Act are discussed: core indicators of performance, additional and existing indicators of performance, state adjusted levels of performance, improvement plans and sanctions, annual report, and national activities. Section 3 discusses comparability of data elements and definitions and barriers to the implementation of the acts. Two matrixes compare the data requirements and definitions contained in the acts.
