THE NATIONAL CENTER FOR EDUCATION EVALUATION (NCEE) IN THE INSTITUTE OF EDUCATION SCIENCES INTENDS TO AWARD A CONTRACT FOR AN IMPACT EVALUATION OF MANDATORY-RANDOM STUDENT DRUG TESTING IN HIGH SCHOOL GRADES 9-12 THAT RECEIVE GRANTS FROM THE OFFICE OF SAFE AND DRUG FREE SCHOOLS (OSDFS) IN ITS FY 2006 COMPETITION. THE FOCUS OF THE EVALUATION IS ON PROGRAM IMPLEMENTATION AND DATA COLLECTION BETWEEN FEBRUARY 2007 AND JUNE 2008. WHILE TREATMENT SCHOOLS MAY ANNOUNCE AND PROMOTE THEIR PROGRAMS UPON NOTIFICATION OF THEIR ASSIGNMENT STATUS, THE SCHOOLS MAY CHOOSE TO BEGIN MANDATORY RANDOM DRUG TESTING EITHER IMMEDIATELY AFTER AWARD (SPRING 2007) OR AT THE BEGINNING OF THE 2007-08 SCHOOL YEAR. THE CONTRACTOR WILL CONDUCT FOLLOW-UP STUDENT SURVEYS IN FALL 2007 AND SPRING 2008 IN BOTH TREATMENT AND CONTROL SCHOOLS. CONTROL SCHOOLS ARE PROHIBITED FROM ANNOUNCING, PROMOTING, OR IMPLEMENTING DRUG TESTING UNTIL AFTER THE SPRING 2008 SURVEY IS CONDUCTED. DATA COLLECTION FOR THE ENTIRE SAMPLE WILL BE COMPLETED BY THE END OF THE 2007-08 SCHOOL YEAR. IN AUGUST 2006, OSDFS PLANS TO AWARD APPROXIMATELY 10 TO 15 NEW GRANTS, AND THESE GRANTS ARE EXPECTED TO INCLUDE AT LEAST 30 PARTICIPATING SCHOOLS.
