WORTH NOTING ON TV

* SATURDAY

Olympic Winterfest: Countdown to Lillehammer (CBS, 4:30-6 p.m.): Three and a half months from now, world attention will be focused on the Olympic skating competition at the Northern Lights Hall in Hamar, Norway - part of the roughly 120 hours that CBS will be airing of the 1994 Olympic Winter Games in Lillehammer, Feb. 12-27.

Meanwhile three of these ``Winterfest'' programs are covering an event from the same hall - the so-called Piruetten competition. It's the only shot Olympic hopefuls have to compete on this ice prior to the Winter Games, and the Piruetten event includes Olympic winners and other top skating figures like 1992 bronze medalist Nancy Kerrigan of the United States, and Natalia Mishkutenok and Artur Dmitriev of Russia. US champion Scott Davis is also competing, along with several other bright lights.

Scott Hamilton, CBS Sports' figure skating analyst, will call the competition with Verne Lundquist and Tracy Wilson. (The other two Piruetten shows air Nov. 6 and 13.) * SUNDAY

This Week With David Brinkley (ABC, 11:30 a.m. to 12:30 p.m., E.T.): This special edition of Sunday morning's most-watched news program takes a look at the Clinton administration's performance - both domestic and foreign - one year after his election. Host Brinkley and his regular panel - Sam Donaldson, George Will, and Cokie Roberts - are joined by Gov. Mario Cuomo (D) of New York and Gov. William Weld (R) of Massachusetts.

The subject of the special may be a predictable one, but its setting is something of a surprise: Norman Rockwell's working studio on the grounds of the museum named for him in Stockbridge, Mass. It opened to the public April 3. * MONDAY

High School Student Forum (C-Span, 8-9 p.m., E.T.): From the Walt Whitman High School in Montgomery County, Ala., Secretary of Education Richard Riley takes part in a discussion with students.
