I build measurement for settings where the questions are specific and the stakes are real. Working adults returning to training. Online learners earning a degree at eleven at night. Leaders learning to read a team that does not think like they do. Two organizations deciding whether they can actually work as one.

Independence
Sims Praxis, LLC is an independent consulting practice, wholly separate from any employer. I serve as Vice President of Learner Success and Retention at Indiana Wesleyan University National and Global. Indiana Wesleyan University does not endorse, sponsor, support, or participate in any Sims Praxis engagement. No university resources, personnel, data, or facilities are used in this work, and no Sims Praxis client relationship implies any relationship with the university.

Background

Why I write my own instruments

I spent years watching organizations make consequential decisions from data that could not support them. Programs reported participants without agreeing on what a participant was. Retention efforts targeted everyone equally because nothing told them where risk actually sat. Satisfaction surveys came back positive while people quietly left.

The available instruments were built for other settings. Most were normed on traditional undergraduates or on general corporate samples. Applied to a workforce program serving adults balancing jobs, children, and transportation, they asked about the wrong things and left out the ones that decided who finished.

So I built my own. Five instruments now, each grounded in established theory, each written for a population I have actually worked with, and each moving through formal research review rather than being published to a website and called validated.

Formal validation takes longer than self-publication. It is also the only path to a claim that holds up under scrutiny, which is the standard I want these instruments held to.

The five instruments look unrelated until you trace them back to the same question. My dissertation examined how social identity heuristics shape cognitive empathy, meaning how the categories we assign to people change how accurately we read them. That finding runs underneath everything I have built since. Belonging is a question of whether an institution reads you correctly. Leadership quality is a question of whether a manager reads their staff correctly. A merger succeeds or fails on whether two organizations read each other correctly. Different settings, one mechanism.

Application

Where this work goes

Education
Persistence and departure risk among adult and online learners, where residential-student instruments consistently measure the wrong things. SBIIS · PPRRS-WA
Workforce
Retention risk in training and program settings, including the situational and family pressures that drive most adult attrition and rarely appear on a satisfaction survey. PPRRS-WA
Leadership
Identity-differentiated perspective-taking practice across race, gender, generation, and socioeconomic difference. Built for development and coaching, where the value is in showing a leader where deliberate practice drops off and habit takes over. LCEP
Mergers and acquisitions
Cultural compatibility between two organizations before the deal closes. Both sides complete identical items and the gap scores locate integration risk while it can still be planned for, rather than after key staff have already left. PACCI
Organizational readiness
Whether an organization can absorb a technology change, measured across leadership vision, staff capability, data governance, and change capacity rather than assumed from enthusiasm in the room. OAIRS

How I work

What you can expect

Honest status
Every instrument’s development stage is stated plainly in every proposal and report. Nothing is described as validated before it is.
No identifiable data
Your organization holds identity and transmits coded records. The key linking code to person never leaves your hands.
Fixed-fee scopes
Engagements are priced as deliverables rather than hours, so the cost is known before the work starts.
Plain reporting
Findings are written for the people who have to act on them. Statistical detail lives in an appendix, not in the summary.
A real answer on fit
If an instrument is not the right tool for your question, I will tell you that in the first conversation.

Let’s talk about what you need to measure

Bring the population, the decision the data has to support, and the timeline. Thirty minutes is usually enough to know whether there is a fit.
