Analyzing your data is a process in which you will want to involve your entire staff. There are a number of variables that will help you determine the best strategy for your school including the size of staff, organization of teams, availability of computers and speed of Internet connection, and the amount of staff meeting time.
The critical piece is that you model the importance of data analysis and that you involve (mandate) all staff in the process. The odds of your teachers making the instructional changes needed for improved student achievement are much greater when they examine the data and discuss what it tells them about current achievement.
A process recommended for data analysis of the AYP, MSA or HSA data is that you assign teams of teachers (grade level, interdisciplinary, department, or random) the detailed analysis of one of the testing areas using the AYP, MSA or HSA data online. For example, a middle school principal might assign the interdisciplinary teams to analyze the reading scores whereas the math team would analyze the math scores, the science team would analyze the science scores, etc.
The assignment could be given at a staff meeting where the principal introduced some key results of AYP, MSA or HSA performance using the web site to show selected graphs or using transparencies printed out from the web site. This overview should focus on both areas of strength and need and disaggregated as well as aggregated data. Low performing schools may need to dig a little deeper for areas to celebrate. Be sure to note trends of improvement even when the target was not met. You might also discuss the team data analysis assignment more specifically so that everyone is clear on the process and expected end products.
The teams would be expected to complete their data analysis at a regularly scheduled team time (if there is a regularly scheduled time). They would be expected to report back their findings at an upcoming staff meeting so that all staff would get a complete picture of the student performance at their school.
You will now need to map out a game plan for your school that will include outcomes, activities, a timeframe, meeting format and audience.
