Narrative:
Aircraft X climbed to 3000 ft. I thought I climbed aircraft X to 5000 ft. I wrote 5000 ft on the strip. I had mistakenly said '15000 ft' to aircraft X. I called traffic that was 2 O'clock position; 10 mi; level at 6000 ft. Aircraft X reported the traffic in sight when he was around 4000 ft. When I observed aircraft X leaving 5300 ft; I told him to descend and maintain 5000 ft.

Title: PCT CTLR EXPERIENCED OPERROR AT 5500 FT WHEN ISSUING CLB CLRNC THROUGH OCCUPIED ALT.
Narrative: ACFT X CLBED TO 3000 FT. I THOUGHT I CLBED ACFT X TO 5000 FT. I WROTE 5000 FT ON THE STRIP. I HAD MISTAKENLY SAID '15000 FT' TO ACFT X. I CALLED TFC THAT WAS 2 O'CLOCK POS; 10 MI; LEVEL AT 6000 FT. ACFT X RPTED THE TFC IN SIGHT WHEN HE WAS AROUND 4000 FT. WHEN I OBSERVED ACFT X LEAVING 5300 FT; I TOLD HIM TO DSND AND MAINTAIN 5000 FT.
