NUMATS has something related to this on their website. For 5th and below, they recommend only the PSAT 8/9, although I suppose that might depend on what level of curriculm your DD is at. For 6th graders this year they had the following:

First-Time Testers
If grade-level test
results* were: =90th-94th percentile
Should take: PSAT 8/9
If grade-level test
results* were: ≥95th percentile
May take: PSAT 8/9, SAT and/or ACT
Subsequent Testers
Considerations: EXPLORE scores in grade 5 were below 21 in reading and math AND below 19 in composite
Should take: PSAT 8/9
Considerations: EXPLORE scores in grade 5 were 21 or above in reading or math OR 19 or above in composite
Should take: SAT and/or ACT
*verbal/reading, mathematics or composite
Next year I would imagine their recommendation will include PSAT 8/9 scores for that determination instead of EXPLORE. (I have no idea what the equivalent of a 21 or 19 would be on the PSAT 8/9)
