Jackett's team have picked up 13 points from their opening five matches, and the former Millwall boss has revealed that he expects the level of their performances to continue.
The 51-year-old told the Express & Star: "If we drop our standards, even by 5%, that could be the difference between winning and losing, because the only comfortable game that we've had so far has been Gillingham.
"Every other match has been tight and competitive and the opposition has pushed us all the way. We have to keep our standards high and make sure that we get everything out of our players."
Wolves host Swindon Town at Molineux on Saturday.
