Narrative:

This deviation occurred while descending to 9000 ft on the initial descent phase of an approach to runway 23L at cle. Conditions during the final part of this descent were (in and out of clouds and light/moderate chop) partial IFR. Toward the final part of this descent (leveloff) which the first officer was flying my attention was diverted on a readback of a clearance from approach and a frequency change. I as captain did not monitor leveloff phase of a relatively new first officer in a B737-200. When I looked up I saw the altitude approaching 8700 ft. We both stopped the descent and climbed to 9000 ft assigned altitude. There was no mention of this deviation by approach control. Lesson: stay attentive at all times. Fly fist at all times.

Title: ALT OVERSHOOT DURING APCH TO CLE, OH, IN IMC CONDITIONS WITH INEXPERIENCE FO FLYING.

Narrative: THIS DEV OCCURRED WHILE DSNDING TO 9000 FT ON THE INITIAL DSCNT PHASE OF AN APCH TO RWY 23L AT CLE. CONDITIONS DURING THE FINAL PART OF THIS DSCNT WERE (IN AND OUT OF CLOUDS AND LIGHT/MODERATE CHOP) PARTIAL IFR. TOWARD THE FINAL PART OF THIS DSCNT (LEVELOFF) WHICH THE FO WAS FLYING MY ATTN WAS DIVERTED ON A READBACK OF A CLRNC FROM APCH AND A FREQ CHANGE. I AS CAPT DID NOT MONITOR LEVELOFF PHASE OF A RELATIVELY NEW FO IN A B737-200. WHEN I LOOKED UP I SAW THE ALT APCHING 8700 FT. WE BOTH STOPPED THE DSCNT AND CLBED TO 9000 FT ASSIGNED ALT. THERE WAS NO MENTION OF THIS DEV BY APCH CTL. LESSON: STAY ATTENTIVE AT ALL TIMES. FLY FIST AT ALL TIMES.
