Creation of the Database

			Creating the Meta Data and File Documentation Merging Files

The data processing conducted by the NAEP materials and scoring staff for each assessment results in the transmittal to the NAEP data analysts of four data files for each grade assessed. These four data files are based on
data collected from the following questionnaires:

• student booklets,
• teacher questionnaires,
• school characteristics and policies questionnaires, and
• SD/LEP questionnaires.

In addition to these files, sampling weights must be included in order to make valid statistical inferences about the population of students and schools included in NAEP assessments. These files are merged into the final database.
