Parkinson's side, promoted via the play-offs in May, had to come from behind to preserve their unbeaten home record this season in a 2-2 draw with Colchester.
"We know everything isn't going to go our way at home as it had been doing in our previous games," Parkinson said after Nahki Wells had headed his second goal of the game and ninth in eight games to earn the Bantams a point.
"You're going to get goals and decisions against you. But when you do, you have to find something within you as a team to come back and I was so pleased we did that.
"It was a really good test for us and we came through it well. It was a great game to be involved in and I'm sure, like me, the fans will go home knowing they have seen a good spectacle.
"You can sense from games like this that the level of quality from the teams we are playing against has obviously gone up from last season.
"I'm so pleased with the lads though. The level of spirit among them is just where it should be and that will stand us in good stead."
