Narrative:

We were departing dtw with the first officer flying -hand, not autoplt - and he was attempting to level off at 10000 ft MSL. He leveled at 10000 initially, and then I observed the aircraft enter a slow climb. At 10100 ft I repeatedly called the altitude to his attention, but he did not stop the climb. At 10200 ft the TCASII sounded a warning to 'monitor vertical speed' in response to another aircraft that was approaching from the right at 11000 ft. I took our aircraft and returned to 10000 ft. Later the first officer told me his altimiter had stuck or hung up at 10000 ft indicated. He said he hadn't hadn't been able to figure out what I was talking about, and although it is customary to level off on the captain's altimeter, he never looked at my side of the cockpit. He also didn't notice his ivsi was indicating a climb. It was a disappointing performance for a first officer with 9 yrs of experience.

Narrative: WE WERE DEPARTING DTW WITH THE FO FLYING -HAND, NOT AUTOPLT - AND HE WAS ATTEMPTING TO LEVEL OFF AT 10000 FT MSL. HE LEVELED AT 10000 INITIALLY, AND THEN I OBSERVED THE ACFT ENTER A SLOW CLB. AT 10100 FT I REPEATEDLY CALLED THE ALT TO HIS ATTN, BUT HE DID NOT STOP THE CLB. AT 10200 FT THE TCASII SOUNDED A WARNING TO 'MONITOR VERT SPD' IN RESPONSE TO ANOTHER ACFT THAT WAS APCHING FROM THE R AT 11000 FT. I TOOK OUR ACFT AND RETURNED TO 10000 FT. LATER THE FO TOLD ME HIS ALTIMITER HAD STUCK OR HUNG UP AT 10000 FT INDICATED. HE SAID HE HADN'T HADN'T BEEN ABLE TO FIGURE OUT WHAT I WAS TALKING ABOUT, AND ALTHOUGH IT IS CUSTOMARY TO LEVEL OFF ON THE CAPT'S ALTIMETER, HE NEVER LOOKED AT MY SIDE OF THE COCKPIT. HE ALSO DIDN'T NOTICE HIS IVSI WAS INDICATING A CLB. IT WAS A DISAPPOINTING PERFORMANCE FOR A FO WITH 9 YRS OF EXPERIENCE.
