Once Focused on System Problems, Principal Supervisors Now Drive Support

Des Moines schools chief Thomas Ahart discusses how his district re-made the principal supervisor job
July 28, 2020 7 Min Read

In 2014, Des Moines Public Schools was one of six urban school districts selected to participate in Wallace’s Principal Supervisor Initiative, a four-year effort to overhaul a central-office position from its traditional focus on administration to a focus on developing principals’ skills at supporting effective teaching. Des Moines, which serves 33,000 children across more than 60 schools, was eager to get to work.

A year earlier, newly appointed superintendent Thomas Ahart had increased his staff of supervisors, known in the district as directors, to five from three, thereby reducing the number of schools each supervisor oversaw. At the time, a single director managed all of the district’s 39 elementary schools. Over the course of the effort, Des Moines made substantial changes that allowed principal supervisors to spend more time working alongside principals to strengthen their instructional leadership practices. A new report, Changing the Principal Supervisor Role to Better Support Principals: Evidence from the Principal Supervisor Initiative, describes the experiences of Des Moines and the other districts, as well as the impact of the work. In early March, Ahart sat down with us to discuss how the supervisor effort had unfolded in Des Moines and his plans to keep the momentum going. The interview has been edited for length and clarity. 

One of the key components of the Principal Supervisor Initiative (PSI) was to strengthen central office structures to support and sustain changes in the principal supervisor’s role. How did you accomplish this in Des Moines?

Prior to the PSI grant, we had a central-office structure that supervised schools, not principals. In theory, our principal supervisors evaluated principals, but what they really did was help principals solve problems with the system, whether it involved facilities, business and finance, human resources. Then at the end of the year, they did an evaluation that, from my own experience as a principal, was of very little value.

Frankly, it just checked a box.

When we started to break down how to better support our schools, the big challenge was: How do we take care of the things currently on the principal supervisor’s plate that detract from coaching around student growth? That was the driver in shifts made holistically at central office. Rather than principal supervisors brokering resources from the district for their principals, we needed a system that allowed that to happen organically.

So what changes did you make?

We created a cadre of five principal supervisors called directors and put each in charge of a network of schools. They [originally] reported to two executive directors who served as a go-between between the rest of the central administration and the schools. I’m embarrassed that I didn’t figure this out earlier, but we soon recognized a problem with this solution. Why were we relegating executive directors, bright people with years of experience in the district, to this type of work? It was true that they knew the system inside and out, and had relationships to navigate it, but their work wasn’t contributing to a more powerful system.

That’s when we created a structure in which each principal supervisor has a district support team for their school network. Each of them has one point of contact in human resources, business and finance, operations and other central-office departments. These [central-office] individuals now hear the whole range of questions, frustrations and wants from principals relative to their department, and they’re going back to their [department heads] with really good thinking about how to make their department work better. This is a paradigm shift in how the central office functioned. In the past, departments like business and finance never felt connected to what was happening in schools. The new structure makes them feel like, hey, I’m not just pushing numbers. I’m a critical piece of making this work at the classroom level. They’re motivated and highly engaged. Interestingly, we now have principals inquiring about openings in human resources. We’ve never had that before, so I think that’s a positive development.

The job description of a principal supervisor has been completely rewritten in Des Moines. How did you manage the change in expectations for the role?

I became associate superintendent for teaching and learning in 2011, and 10 months into it, I was named interim superintendent. By the time I was appointed superintendent in 2013, I already had been working on a different organizational strategy. I drafted a new org chart and showed it to the three directors who were supervising schools at the time. Their eyes got really big and they said, what about us? I said, great question, tell me what you do right now. They said they supported schools and described the brokering role I mentioned earlier. Then I showed them the monitoring reports I submit to the board of education every year and asked them to which ones they contributed. They looked at each other and said none. That’s the problem, I told them. These guys were working really hard, feeling like they were doing everything for our schools and principals, but it didn’t show up anywhere on paper. They didn’t own anything, and that actually did them a great disservice in terms of how the position was viewed by the rest of the organization.

After I became superintendent, I hired two more directors and gave them each smaller networks of schools. Both had been sitting principals, both were dedicated to students, but they had no idea what they were doing as supervisors. In terms of coaching, they had a lot of work to do. Shortly after, the grant application for the PSI came about. It was perfect timing. The PSI provided us the resources to put in place a leadership framework and an instructional framework, and to develop shared language and shared expectations. It allowed us to support our principal supervisors so they can coach effectively and take a different coaching disposition based on the problem of practice they’re trying to solve.

According to the report, over the course of the PSI initiative principals reported that the quality of the evaluation feedback they received from their supervisors improved. How has the culture around evaluations changed in Des Moines?

A number of big changes have happened. First, our principals now receive a meaningful evaluation, whether they like it or not. It’s much more integral to their work with their supervisors. They also have much more clarity about their job and the system’s expectations for them. They’re not flying blind and then worrying at the end of the school year when someone goes through an exhaustive checklist to determine if they’re doing an okay job. Our principals see their supervisor at least once a week all year. In most cases, they’re spending several hours together each week. So even if they don’t like something in their evaluation, they can’t say it’s not an informed assessment of their practice.

Do you think a principal supervisor can be both coach and evaluator?

We’re still wrestling with that question. I do think an evaluator should have coaching skills. We want the evaluation process to be one of growth and improvement, not punitive. But if my only coach is my evaluator, while he may do a wonderful job in supporting me, I think there are some inherent limits to that when ultimately he has to judge my performance. Right now, we’re working to build coaching capacity in the folks who serve on our network support teams.  

The PSI researchers recommend that districts embed the principal supervisor role within the broader work of the central office to sustain the changes they’ve implemented. What’s your plan in Des Moines?

Currently, our principal supervisors report to the associate superintendent, but we may have them report up through our executive director of teaching and learning instead. Her department is responsible for curriculum and works closely with principals to implement it. We’re at a place now where we’re asking, how many voices do we want in our principal’s ear? By better integrating our work at central office, we can eliminate the number of at least perceived demands on our principals. It would also be further doubling down on the principal supervisor’s ownership of executing district-wide priorities.
