Narrative:
ATC initially cleared flight to 5;000 feet for the departure and this altitude was briefed for the departure. ATC changed the altitude to 2;500 feet on the taxi and the crew dialed the new altitude into the FMS. First officer failed to level off at 2;500 feet and topped out at 3;000 feet before correcting back down to 2;500 feet. ATC gave us a vector away from traffic eight miles ahead of aircraft and gave us a climb up to 15;000 feet. Neither crew member remembers hearing the 1;000 foot prior altitude alert. It should not have been inhibited for a flaps 1 condition. Altitude alert functioned normally on next level off. Crew must have missed the alert due to flaps up call-out. The first officer had only flown 10 times in the last 90 days with 10 landings. The crew should have reviewed the field elevation versus the level off altitude and briefed that the level off would occur immediately after flap retraction. First officer needs to be extra vigilant with flight performance during this time of low flight hours.
