The Kennedy Center announced its selections for the 13th annual American College Theatre Festival yesterday, giving the festival's national playwriting award to a musical for the first time.

The musical is "Going On!" with book and score by Glenn Treibitz, a student at William Paterson College in Wayne, N.J. It will be performed at the Terrace Theater April 1-2, as one of eight college productions brought to the Kennedy Center between March 30 and April 18. Four of the eight are original student works, continuing the new emphasis of last year's choices.

(April 6-8); Sara Nemeth's "Swansong for a Unicorn," a new play from Northwestern University (April 9-10); Darrah Cloud's "The House Across the Street," another new play from the University of Iowa (April 11-12); Paul Sills' "Story Theater," from Saint Michael's College (April 13-15); and "Red Peppers Plus," a revue of Noel Coward material from the University of Illinois at Urbana-Champaign (April 16-18).
