For example, last school year, our executive director of teaching and learning, Jill Johnson, visited a middle school and sat in on a few classes while the teachers taught students about inferences. Based on the lagging data they had on their students, the teachers were pretty confident that, after the first lesson, about 80 to 90 percent of students would understand the concept. But when they assessed students with student response systems, they saw that only about a third of students “got it.” Using that data, the teachers regrouped and tackled the concept again the next day. They tested students again and the proficiency level jumped to around 90 percent.

That experience demonstrated that we can look at lagging data to get a sense of how our students will perform, but we also have to look at current data to help drive our instruction.

Having the ability to immediately view student achievement data also helps with the development of our common assessments. For instance, if we see students struggled with a particular question, we can tell pretty quickly whether it was a good challenging question or a bad question that needs to be rewritten.

Since 2010, our assessment and data management system has become an important part of our continuous improvement model. It helps us make sure people have the information they need to make informed decisions and that this becomes part of their daily practice.

With the ability to access students’ historical performance on state tests and current progress on local assessments, we have the actionable information we need to improve teaching and learning from the individual student level to the district level. Even teachers in our high-performing schools and classes continually review their data to identify which areas they need to focus on and which strands they can improve. And, if there’s one thing we’ve learned, there’s always room for improvement.
