Narrative:

PNF was off of the ATC frequency listening to ATIS as was the acm. Altitude assignment of 8000 ft was given to me along with a frequency change. After frequency change, I heard ATC tell me 'give me a good rate through 10000 ft.' at 9300 ft ATC said 'verify you are maintaining 10000 ft.' ATC then stated that 10000 ft was the assigned altitude. I immediately climbed to 10000 ft. Separation was never lost. I would have verified the assignment if I had any doubt but I thought that I had heard the instruction as stated above. Also, there was no question from the controller, after my repeat back, that I was descending to 8000 ft.

Narrative: PNF WAS OFF OF THE ATC FREQ LISTENING TO ATIS AS WAS THE ACM. ALT ASSIGNMENT OF 8000 FT WAS GIVEN TO ME ALONG WITH A FREQ CHANGE. AFTER FREQ CHANGE, I HEARD ATC TELL ME 'GIVE ME A GOOD RATE THROUGH 10000 FT.' AT 9300 FT ATC SAID 'VERIFY YOU ARE MAINTAINING 10000 FT.' ATC THEN STATED THAT 10000 FT WAS THE ASSIGNED ALT. I IMMEDIATELY CLBED TO 10000 FT. SEPARATION WAS NEVER LOST. I WOULD HAVE VERIFIED THE ASSIGNMENT IF I HAD ANY DOUBT BUT I THOUGHT THAT I HAD HEARD THE INSTRUCTION AS STATED ABOVE.
