Beginning in 2006 the top students have been sent to New York for an additional four-day session, capped by a performance and an awards ceremony.

When she left the building after her first of two four-day sessions, Ms. Chan found a new appreciation for freedom.

But when she left the building after her second four-day session, her opinion had changed.

The three- and four-day sessions combine hands-on field experience with classroom activities.

Fees: $55 for one four-day session or $105 for both, plus a $25 membership fee.

There is also a special four-day session from July 5 through 8 available for $112.

The cost of the four-day session, including room and board, will be $700.

Prices range from $640 to $900 a person, double occupancy, for a four-day midweek session.

The four-day sessions, which meet Thursday through Sunday, cost $450.

Fees are $250 for a week ($200 for the four-day July 3 session).
