This feature
allows you to inform the Assessment Center CAT administration
engine how to administer a CAT instrument accurately according the
algorithm established for that instrument.

An
instrument’s CAT parameters cannot be changed within a study once
that study has been launched.

Default CAT
parameters have been set for all administered CAT instruments in
Assessment Center. If you utilize an administered CAT instrument in
a study, you will have the option of modifying the default CAT
parameters.
Prior to
initial data collection, you must set CAT parameters for your
custom CAT instruments. The CAT parameters you set for a custom CAT
instrument will become the default parameters for that
instrument. Other users utilizing your custom CAT instrument
will have the option of using the default parameters or modifying
them to their specifications.
