Conversely, high-quality preparation programs have rigorous selection processes to ensure that candidates are ready and planning to become administrators. For example, in Illinois, principal preparation program candidates are required to have an in-person interview with at least two full-time faculty members and create an extensive portfolio of teaching achievements. 28 High-quality programs also partner with districts to identify potential leadership candidates. 29 The New York City Aspiring Principals program at the New York City Leadership Academy identified emerging teacher leaders to participate in their program, leading to meaningful improvements in student achievement at schools where program graduates were hired. 30 Residencies, mentorships, and cohort models that provide meaningful school- based experiences are components of effective preparation programs. Much like in the medical profession, prospective principals need meaningful on-the-job experiences throughout their training to ensure they are prepared for the diverse demands of the job. High- quality principal preparation programs not only require candidates to observe 13 existing principals but also engage with those principals in a wide range of meaningful activities. Some programs even provide full-time paid residencies for principal candidates so they can be fully immersed in the job for an entire year before graduating the program. 31 Having meaningful on-the-job experiences for candidates requires partnerships with districts and the selection of high-performing principal mentors who can provide support for candidates during their preparation and first years on the job. 32 A strong cohort model can also provide principal candidates with support. Program cohorts participate in classes and start their principalship with the same group of candidates. Novice principals can then consult this built-in network of fellow principals for support throughout their careers. 33 While there is little data about the effectiveness of principal preparation programs, a few programs have track records of training better principals and filling shortages in hard-to-staff areas. In 2010, Illinois began requiring programs that train principals to incorporate many of the characteristics of high-quality
