First officer, receiving training on medium large transport from captain, was given clearance to descend to 17000 ft. While descending captain put his head down to check radar position to thunderstorm and missed the 1000 ft call. When captain looked up he noticed their altitude descending through 16000 ft. Controller questioned their altitude as they were climbing back to assigned.

Narrative:
It was training flight with first officer flying. We were cleared to 17000 ft. The first officer started his descent. He said we were out of 'X altitude to 17000 ft.' I start to resume 18000 ft checklist and was watching radar position to thunderstorm in and around airport. Neither myself nor first officer called 1000 ft to go. When I looked up we were through 16000 ft. I took the aircraft and returned to 17000 ft. Controller asked about altitude in climb back to 17000 ft and cleared us to 11000 ft. We can't break good operational practices because of WX of cockpit workload. The 1000 ft call would have gotten both of us on track.

Title: FO, RECEIVING TRAINING ON MLG FROM CAPT, WAS GIVEN CLRNC TO DSND TO 17000 FT. WHILE DSNDING CAPT PUT HIS HEAD DOWN TO CHK RADAR POS TO TSTM AND MISSED THE 1000 FT CALL. WHEN CAPT LOOKED UP HE NOTICED THEIR ALT DSNDING THROUGH 16000 FT. CTLR QUESTIONED THEIR ALT AS THEY WERE CLBING BACK TO ASSIGNED.
Narrative: IT WAS TRAINING FLT WITH FO FLYING. WE WERE CLRED TO 17000 FT. THE FO STARTED HIS DSCNT. HE SAID WE WERE OUT OF 'X ALT TO 17000 FT.' I START TO RESUME 18000 FT CHKLIST AND WAS WATCHING RADAR POS TO TSTM IN AND AROUND ARPT. NEITHER MYSELF NOR FO CALLED 1000 FT TO GO. WHEN I LOOKED UP WE WERE THROUGH 16000 FT. I TOOK THE ACFT AND RETURNED TO 17000 FT. CTLR ASKED ABOUT ALT IN CLB BACK TO 17000 FT AND CLRED US TO 11000 FT. WE CAN'T BREAK GOOD OPERATIONAL PRACTICES BECAUSE OF WX OF COCKPIT WORKLOAD. THE 1000 FT CALL WOULD HAVE GOTTEN BOTH OF US ON TRACK.
