Narrative:
Cruising en route from elp to hou, center called us 300 ft low on altitude. I was letting my back seat crew (flight engineer) get flying experience in a T38. He was maintaining overall good altitude control, but on this occasion allowed our altitude to go about 250 ft low. When center called, I didn't think that we had been 300 ft low. However when I looked at my altimeter, I realized that I had not reset my altimeter to 29.92 on the climb out and still had the 30.04 from our departing airport. We had a little WX and some traffic calls on climb out that apparently was enough distraction to miss setting the altimeter.

Title: PLT OF A GOV T38 TALON FAILED TO RESET THE ACFT'S ALTIMETER CLBING THROUGH FL180 RESULTING IN BEING 300 FT LOW AND ARTCC RADAR CTLR INTERVENTION TO CALL ATTN TO THE LOWER THAN ASSIGNED CRUISING ALT.
Narrative: CRUISING ENRTE FROM ELP TO HOU, CTR CALLED US 300 FT LOW ON ALT. I WAS LETTING MY BACK SEAT CREW (FE) GET FLYING EXPERIENCE IN A T38. HE WAS MAINTAINING OVERALL GOOD ALT CTL, BUT ON THIS OCCASION ALLOWED OUR ALT TO GO ABOUT 250 FT LOW. WHEN CTR CALLED, I DIDN'T THINK THAT WE HAD BEEN 300 FT LOW. HOWEVER WHEN I LOOKED AT MY ALTIMETER, I REALIZED THAT I HAD NOT RESET MY ALTIMETER TO 29.92 ON THE CLBOUT AND STILL HAD THE 30.04 FROM OUR DEPARTING ARPT. WE HAD A LITTLE WX AND SOME TFC CALLS ON CLBOUT THAT APPARENTLY WAS ENOUGH DISTR TO MISS SETTING THE ALTIMETER.
