No, you still have pre-check, they use the same equipment and have to follow the same procedures and train their employees to TSA standard (yeah a bit of a joke).
However since it's a private contractor they have additional motivations which increase efficiency. For example at SFO they use the CCTV and FIDs systems to determine which checkpoints are going to see increased traffic and will proactively shift resources to those checkpoints from the lightly loaded ones. Of course they also creatively used the same CCTV resources to "cheat" on some of the TSA tests.
