PPVT-4: Converting and comparing GSV scores for PPVT-3 and PPVT-4

Frequently Asked Question:

We are using the PPVT-4 in a study.  Some of the students participating in the study were also tested using the PPVT-3 and we have access to those scores.  We would like to run an analysis using the GSV scores, is there anyway to convert PPVT-3 raw scores to GSV scores?

Answer:

Yes, the PPVT-4 Manual provides GSV scores for both the PPVT-3 and PPVT-4.
