Narrative:

We descended through our assigned altitude of 6000 ft while en route to iad. We noticed the deviation after having reached about 5400 MSL and returned to assigned altitude. Factors contributing: we are usually at 5000 ft at this point on the way to iad. Controller had made several changes to altitude assignment. I was busy preparing for approach, completing descent/approach checks, etc and was not monitoring first officer's flying as closely as I should. Autoplt was deferred, increasing cockpit workload.
