GPA Exam Selection Features and Constraints
To ensure that GPA results are valid, GPA has features that constrain exam selection in the following ways:
At Least 3 Compatible Tests Are Required
To run a GPA analysis requires two Baseline tests of the same strategy and at least one Follow-up
exam of a compatible SITA strategy—see
Table 8.1, "Permitted Baseline–Follow-Up Configurations
. The following message will appear if you have selected a GPA printout and
if the tests you selected do not fit this criterion:
Select
PRINT CLASSIC SFA
to print a Classic SFA report, or select
RETURN TO PRINT MENU
to return to
the Print Menu. You cannot run GPA until you have a sufficient number of compatible tests for that
eye.
