A radar developmental controller working a position he had been checked out for only 4 days climbed an air carrier through the altitude of an atx with less than standard separation. Reporter had put an interim altitude in the air carrier data block, but cleared him to a higher altitude by mistake. Apparently the controller was not aware of his error until the conflict alert went off and it was later verified that he erred when the tapes were played back.

Narrative:

Atx Y was going direct to cvg level at 14000 ft. Air carrier X was coming out of day approach at 10000 ft head-on with atx Y. I put an interim altitude of 13000 ft, but I cleared the aircraft air carrier X to FL220. I thought I had issued 13000 ft until the tape was played back to me.

Original NASA ASRS Text

Title: A RADAR DEVELOPMENTAL CTLR WORKING A POS HE HAD BEEN CHKED OUT FOR ONLY 4 DAYS CLBED AN ACR THROUGH THE ALT OF AN ATX WITH LTSS. RPTR HAD PUT AN INTERIM ALT IN THE ACR DATA BLOCK, BUT CLRED HIM TO A HIGHER ALT BY MISTAKE. APPARENTLY THE CTLR WAS NOT AWARE OF HIS ERROR UNTIL THE CONFLICT ALERT WENT OFF AND IT WAS LATER VERIFIED THAT HE ERRED WHEN THE TAPES WERE PLAYED BACK.
