For the last 10 years, the province of Alberta has been engaged in a significant school improvement effort called the Alberta Initiative for School Improvement (AISI). Developed in 1999 through a collaborative process between the Alberta Department of Education and the key stakeholder groups (teachers, school boards, parents, and faculties of education), AISI is starting its fourth three-year cycle of grants and supports to school boards around school improvement. It's among the longest large-scale school improvement programs anywhere. In the AISI model, each school or district develops projects aimed at improving student learning (Alberta has about 60 school districts ranging from very small to quite large). The approach is very much bottom up; AISI defines some areas of interest and goals, but schools and districts define specific projects. The province reviews and funds projects for three years. Total AISI funding is quite modest at about $75 million per year across the province, or a little more than $100 per student (compared to about $10,000 per student per year in total spending in Alberta). An external review of AISI done by an international team of researchers confirms AISI's many strengths, as well as the limits that are partly inherent in using a bottom-up, schoolbased approach and partly common to almost all school improvement strategies. Among its strengths are the high level of commitment to AISI projects by teachers, principals and, often, students and parents. The review said: AISI constitutes a world-class and world-leading example of a systemwide educational strategy. This strategy ... inspires teachers and administrators. It enhances their professional growth and enthusiasm. AISI seeds new, research-informed practices within local communities then spreads them across districts and schools; and it diffuses existing knowledge as well as creating new knowledge. AISI projects meet with a high level of enthusiasm and are largely owned by those who implement them, as opposed to being seen as externally imposed. Given the requirement for educator commitment in any successful education initiative, approaches that build local involvement and learning have much to recommend them. Because every school and district in Alberta has been engaged in some form of school improvement for a decade, improvement work has become an accepted part of what schools do across the province. Although such a claim seems trivial, the reality is that many schools and school systems are focused on maintenance, and not on improvement, so this change in Alberta is significant. Limitations At the same time, the review suggests that AISI exhibits some of the same limitations found in other voluntary, school-based improvement efforts. One challenge is that the level of commitment and understanding of change among schools is highly variable. Some schools may not see the need to change, feeling that any shortcomings are primarily due to the limitations of students. The review found that high schools were much less likely than elementary schools to undertake substantive changes, a finding consistent with a large body of evidence on the challenges of improving high schools. Other schools may focus on changes that have little or no effect on student outcomes. Schools may decide to work on the wrong things--for example, the frequent desire in some schools to focus on improving attendance or behavior instead of improving instruction and engagement leading to better attendance and behavior. The review noted that: [some] sites use AISI funds to extend their already established principles and strategies. They do not use the funds to reflect critically upon goals and interventions that are already in place. AISI has been working gradually to encourage higher-yield strategies, but it remains a voluntary and school-driven approach. …
