AM can directly import SPSS system files (.sav). Select File|Import|SPSS .sav, and the file and all available metadata will be read directly into AM. AM skips all character variables.
Importing from an SPSS file may also require a dictionary file. If you want to use any of the MML procedures for test data, you will need to specify the tests and the item parameters (see Importing AM text import file for more details). When importing a SPSS .sav file the dictionary need only contains information that is not contained in the SPSS file. Specifically, the dictionary contains information about the tests, such as item parameters and the arrangement of items into subtests. AM does not process character variables, and skips over any character variables in the SPSS file. After the initial import, select File|Update Metadata from the File menu to read in the dictionary.
