【正确答案】 1、participation    

【答案解析】[解析] 由题干关键词Doris A. Reed, Association of Supervisory and Administrative School Personnel, administrators定位到倒数第四段：Reed said "... but the administrators are really forced to participate. Because if you're the principal of a school, and your teachers say they want to participate, and you don't, you still have to do all their evaluations." 可知如果教师想要参加这个项目，管理者也别无选择。由于此处需要填名词，故将文中的participate写为名词形式participation。
