CLASS Specialists at Teachstone all take turns providing reliability support to anxious testers. We often see the same mistakes and misconceptions over and over again about how the CLASS works, and as my story below will share, how the behavioral markers fit into the coding process.
Let’s make this right.
I don’t understand how many times I need to see evidence for a behavioral marker to score high. One observer shared with me that she expects at least five instances for each behavioral marker within an indicator. I did the math, and that would require at least 190 examples for a 7 score! Another observer scored differently; if she sees each behavioral marker at least one time, she scores a 7. I’m confused!
It’s no wonder she’s confused! To clear this up, I like to be clear about what the coding process is and isn’t.
Let’s be clear: There is no set number of times you need to see evidence of a behavioral marker. In fact, it's a misconception to score behavioral markers at all. Don’t do it!
Page 15 of the Pre-K CLASS Manual states:
"CLASS is not a checklist and observers should view the dimensions as holistic descriptions of classrooms that fall in the low, middle or high range. In many cases, it is not necessary to see indicators of all markers presented in the description of a given range to assign a score in that range."
We never recommend a certain number of examples (such as five feedback loops in Quality of Feedback) to lead to a conclusive score. Rather than counting back-and-forth exchanges, consider: “Did the child engage with the teacher and learn as a result of this interaction?” Remember, in assigning ranges we must consider depth, frequency, and duration of interactions.
Page 14 of the Pre-K CLASS Manual reads:
"The high-end [behavioral] markers for each dimension reflect good teaching practice; however to score in the high range a classroom does not have to be perfect. There may be one or two things that are less than ideal in a given observation, but if the overall classroom experience is characterized by the markers at the high end, the classroom should be scored that way."
I can hear you thinking, “But how many times do we need to see something to call it “consistent?” If you’ve read this far, you know the answer already: there is no set number of times!
Like a broken record, you will hear CLASS specialists say, “CLASS is not a checklist.” Resist the human urge to turn it into a checklist and treat it like the complex, holistic tool that it is. If CLASS observations were as easy as counting behaviors, they wouldn’t capture the complexity of classrooms in all their infinite glory.

Practice and feedback is the key to CLASS® success. Even the most experienced certified CLASS Observers need practice and feedback to make sure their classroom observations remain fair and accurate. The best way to provide this is to use our Calibration product. Calibration protects your investment in reliable data collection.
Online Calibrations are available for Certified CLASS observers at all 6 CLASS levels. When you purchase an individual calibration, you’ll receive a video to watch and code on your myTeachstone dashboard. After submitting your codes, you’ll get an automated score report and a prerecorded webinar discussing the master codes.
Across the country and around the globe, schools/programs will soon reopen after extended closures due to COVID-19. Those that have remained open are instituting new health and safety practices.. Localities will determine whether to provide in-person, online, or hybrid teaching. Regardless of the model that schools/programs adopt, classrooms will look different now and for the foreseeable future.
As the Community Manager with Teachstone, I have been able to talk to many observers, trainers, coaches, and general CLASS lovers. I have found a common thread among these groups: a desire to connect with other CLASS users and put their CLASS knowledge to use.
We often hear from CLASS Observers that are interested in observing more classrooms. Meanwhile, many organizations—particularly smaller organizations or those doing research studies—don’t have Certified CLASS Observers and are in search of observers in their area.
