PROGRAM ENTRIES ARE DIVIDED INTO FIVE MAJOR CATEGORIES: NATIONAL MODELS, STATE SELECTIONS, HONORABLE MENTIONS, EVALUATED PROGRAMS, AND DESCRIPTIONS OF PREVENTION PROGRAMS. THE LAST CATEGORY CROSS-REFERENCES PROGRAMS FOUND IN THE FIRST FOUR CATEGORIES. IN EACH SECTION ENTRIES ARE IDENTIFIED BY STATE AND LISTED ALPHABETICALLY ACCORDING TO PROGRAM TITLE. EACH ENTRY CONVEYS A MAXIMUM AMOUNT OF INFORMATION TO THE USER: PROGRAM NAME, ADDRESS, CONTACT PERSON, PHONE NUMBER, HOURS AVAILABLE, AND A GENERAL PROGRAM DESCRIPTION. UNIQUE FEATURES AND OPERATIONAL INSTRUMENTS HELP DEFINE THE SUCCESSFUL INGREDIENTS OF THE PROGRAMS. INFORMATION IN THE CATALOG CAN BE USED IN A VARIETY OF WAYS: TO LOOK UP STATE PROGRAMS, TO SCAN FOR PROGRAMS WHOSE GENERAL DIRECTION OR PROCESS IS SIMILAR TO ONE'S OWN, OR TO SELECT NATIONAL MODELS WHICH SEEM TO HAVE GOALS AND RESOURCES APPLICABLE TO THE USER. THE ELEVEN NATIONAL MODELS AND THE STATE PROGRAMS WERE SELECTED BY A NATIONAL PANEL. THE CRITERIA USED WERE INNOVATIVENESS AND DEGREE OF YOUTH PARTICIPATION IN PLANNING, IMPLEMENTATION, REPLICABILITY, AND PROGRAM FORMAT. LOCAL PROGRAMS WERE ALSO CHOSEN BY A NATIONAL PANEL WHICH EVALUTED 650 NOMINATIONS AND CHOSE 90 OUTSTANDING PROGRAMS AND 11 NATIONAL MODELS OF SPECIAL EXCELLENCE. PROGRAMS IN RURAL AREAS OR SERVING MINORITY POPULATIONS WERE ALSO SELECTED, AND THE DIRECTORY HAS A LIST OF EVALUTED PROGRAMS WITH INDIVIDUAL ENTRIES NOTING WHEN AND BY WHOM THE PROGRAMS WERE EVALUATED.
