to the public• Provide indicators on the status and trends in
education• Report on the condition of education to Congress,
state policymakers, educational practitioners, the media, and the public
• Assist states and school districts in improving their statistical systems

– The rows are individual institutions– User defines the columns by selecting other IPEDS
variables
• The DAS…– Is a table generator– Which produces aggregated data– The user creates or modifies table parameter files (TPFs)
by tagging: • Row variables• Column variables and specifying• Spanner variables, Filters, etc.

• The vehicle for public access to education survey data collected by the U.S. Department of Education.
• Comprehensive source for tables, findings, and reports generated by NCES researchers.
• Data Analysis System On Line (DASOL) enables users to generate their own tables.

IPEDS data is available in DAS for 2002, 2003, and 2004.
This is adjudicated data that can be used to generate national, regional, and state totals and averages.

Steps for Creating a TableSteps for Creating a Table
• Specify row variables
• Specify column variables
• Specify qualifying values, if necessary
• Run the resulting table parameter file (TPF)
The process of selecting your variables is
called “tagging.” A tag tells DASOL how to
use each variable in building the table.

The directory tree structure of the variables list expands to show the variables that are stored under each of the major headings. A “plus” sign indicates there are variables listed under the heading. Once the heading is expanded a “minus” sign indicates the list has been expanded.

DAS Online Exercise #1DAS Online Exercise #1
The first exercise shows you how to create a simple table of total headcount enrollment by Carnegie Classification and save the table parameter file (TPF) to your drive.
The top section of your report shows total headcount enrollment by Carnegie Classification, and the bottom section shows the number of schools in each classification.

The second exercise shows you how to import and edit the TPF you just saved so you can group the Carnegie Classifications into fewer categories.
This report has the same structure, but both sections reflect the categories just created.
