To educate is to change. Instruction and learning are about change. Educational measurement is defined by variance. Literally. The fundamental concepts in the field are expressed in terms of variance. One of the first techniques that we learn as eager young graduate students is analysis of variance. Without variance, our lives as psychometricians, much likeContinue reading “Vive La Variance!”

Adrift at “C” with IRT
For the past three decades we have weathered the storm of test-based accountability in a skiff called IRT. Buttressed only with a few psychometric tools, loosely defined unidimensional latent constructs, and the promise of measurement invariance we have been buffeted by wind and waves, sometimes taking on water, sometimes finding ourselves run aground in shallowContinue reading “Adrift at “C” with IRT”
We’ve Come A Long Way, Baby!
It’s Saturday morning. The weekend lies before me. We might take the yacht up the river and allow ourselves to be enraptured by the foliage as it envelops us, or head over to the club for some golf, tennis, or one of the other myriad activities that well-to-do white folks engage in before ski season.Continue reading “We’ve Come A Long Way, Baby!”
Render Unto Caesar What Is Caesar’s
How do you innovate in large-scale state testing while continuing to meet federal assessment and accountability requirements? That, essentially, was the question addressed by the Center for Assessment team and state leaders in the final session of the Center’s virtual Reidy Interactive Lecture Series (RILS). Specifically, the session featured interviews with leaders in states currentlyContinue reading “Render Unto Caesar What Is Caesar’s”
Stuck In The Middle With You
Clowns to the left of me! Jokers to the right! Here I am stuck in the middle with you. Read the headlines, listen to podcasts, or chat in line while waiting to show your vaccine card and you might come away with the impression that everything in education revolves around assessment. The root of everythingContinue reading “Stuck In The Middle With You”
On a Whim and a Prayer
You win a multi-year contract for a new, innovative state assessment program. You spend the next six months staffing up, getting the project infrastructure in place, and working with the state to begin the initial design and development process. A new governor takes office and the assessment program and your contract are canceled immediately. MuchContinue reading “On a Whim and a Prayer”
Ed Reform – The Song That Doesn’t End
This is the song that doesn’t end Yes, it goes on and on my friend. Some people started singing it Not knowing what it was. And they’ll continue singing it forever just because [repeat ad infinitum] Well, folks weren’t too receptive of my attempt to invoke Friedrich Nietzsche in a recent post on Education ReformContinue reading “Ed Reform – The Song That Doesn’t End”
Work the Problem
With the Olympics coming to an end, I began browsing through the rest of the Peacock app and came across the recently added 1995 film, Apollo 13. Since first renting the film at Blockbuster as soon as it went to VHS, I must have watched it two dozen times. For some reason, I feel aContinue reading “Work the Problem”
Enough Room Now For 49 Stars
You’re a grand old flag You’re a high-flying flag And forever in peace may you wave As the Olympics shift from the pool and the gym to the track, we are probably in a peak period for thinking about the flag. I’ll admit that aside from the Olympics, holidays like Memorial Day and Independence Day,Continue reading “Enough Room Now For 49 Stars”
It Was A Privilege
The focus recently on opportunity-to-learn, equity, access to a high-quality education, etc. makes me think about my father. Today would have been his 89th birthday and his entire life was a testament to the importance of access to a quality education and to making the most of that access when it was presented to you.Continue reading “It Was A Privilege”
