Narrative:
Center cleared us to descend to 6000 and intercept lda 26 approach. First officer misinterpreted clearance as 'cleared for lda 26 approach' and changed altitude selector to 3000'. After setting my flight director to inbound course, I noticed the aircraft had descended to 5400' and advised first officer to climb back to 6000'. Altitude deviation caused no traffic problems. I feel that descent clearance should have been stated as 'descend and maintain 6000, intercept lda 26L localizer'. Also, both pilots should agree on altitude settings. As a side note: CRM programs seem to lead to less discipline in cockpit. First officer are changing switch settings and performance computers, etc on their own and not consulting with capts.

Title: ACR MLG ALT DEVIATION EXCURSION FROM CLRNC ALT IN ANTICIPATION OF STARTING STAR.
Narrative: CENTER CLRED US TO DSND TO 6000 AND INTERCEPT LDA 26 APCH. F/O MISINTERPRETED CLRNC AS 'CLRED FOR LDA 26 APCH' AND CHANGED ALT SELECTOR TO 3000'. AFTER SETTING MY FLT DIRECTOR TO INBND COURSE, I NOTICED THE ACFT HAD DESCENDED TO 5400' AND ADVISED F/O TO CLIMB BACK TO 6000'. ALT DEVIATION CAUSED NO TFC PROBLEMS. I FEEL THAT DSCNT CLRNC SHOULD HAVE BEEN STATED AS 'DSND AND MAINTAIN 6000, INTERCEPT LDA 26L LOC'. ALSO, BOTH PLTS SHOULD AGREE ON ALT SETTINGS. AS A SIDE NOTE: CRM PROGRAMS SEEM TO LEAD TO LESS DISCIPLINE IN COCKPIT. F/O ARE CHANGING SWITCH SETTINGS AND PERFORMANCE COMPUTERS, ETC ON THEIR OWN AND NOT CONSULTING WITH CAPTS.
