Narrative:
On climb out, leveled at FL210. First officer's altimeter read FL220. Captain's (mine) altimeter was set to 29.82 instead of 29.92. Reset altimeter and descended to FL210. Altimeter was set low by maintenance and missed on preflight due to rushed departure. Contributing factors: first officer was brand new to position and noticed a problem, but did not speak up! Supplemental information from acn 447130: maintenance set captain's altimeter to 28.92. First officer set 29.92. Captain leveled off at FL220 instead of FL210. I was getting ATIS for cle and didn't catch it in time. Momentary altitude of FL220 was reached before immediately descending to FL210.

Title: FLC LEVELS OFF AT CRUISE ALT 1000 FT ABOVE ASSIGNED ALT BECAUSE ALTIMETER WAS SET TO INCORRECT PRESSURE.
Narrative: ON CLBOUT, LEVELED AT FL210. FO'S ALTIMETER READ FL220. CAPT'S (MINE) ALTIMETER WAS SET TO 29.82 INSTEAD OF 29.92. RESET ALTIMETER AND DSNDED TO FL210. ALTIMETER WAS SET LOW BY MAINT AND MISSED ON PREFLT DUE TO RUSHED DEP. CONTRIBUTING FACTORS: FO WAS BRAND NEW TO POS AND NOTICED A PROB, BUT DID NOT SPEAK UP! SUPPLEMENTAL INFO FROM ACN 447130: MAINT SET CAPT'S ALTIMETER TO 28.92. FO SET 29.92. CAPT LEVELED OFF AT FL220 INSTEAD OF FL210. I WAS GETTING ATIS FOR CLE AND DIDN'T CATCH IT IN TIME. MOMENTARY ALT OF FL220 WAS REACHED BEFORE IMMEDIATELY DSNDING TO FL210.
