After more than two decades of work, The Course is being made available to all.
Informational learning pours more content into a container which stays the same size. Transformational learning grows the container itself — the mind that does the knowing. The Course’s learning is the second kind.
Dribbling, throwing, hitting, swinging — separate skills, trained separately. Improved hand-eye coordination raises all of them at once. Developing the self-authoring and self-transforming levels of mind is a bit like that, for one's life: one developmental capacity enhances many — with each correlated connection between them having been documented in published research.
Development is individual. No outcome is promised to every learner. One study is one study — replication is planned.
THE EVIDENCE, IN FULL ↓For the body, the lever is universal and it has always worked: with aerobic exercise we move, and capacity grows — in any country, at any age, on any equipment. The adult mind can make two great further passages — from the socialized to the self-authoring mind, and from the self-authoring toward the self-transforming mind — and yet, until now, we have had no reliable technology and no trustworthy intervention to promote that growth.
Move it, and it grows. Any country. Any age. Any equipment. The lever works on everyone, and the growth can be measured.
Adult growth is typically slow, if it happens at all. A few occasionally transform significantly — but even then, the lever responsible cannot be identified, let alone repeated.
Twenty-nine countries, six years, six disciplines: in its concluding report, the OECD's DeSeCo inquiry distilled what a successful modern life requires to one meta-competency — the self-authoring mind.
And yet, in a sample drawn to represent the general adult population, 78% had not developed the self-authoring mind (Kegan, 1994) — and the proportion does not approach a majority even in highly educated and privileged samples.
No scalable intervention had ever been shown to promote this growth. So while the demand side is settled science, the supply side stood empty — until now.

Sixteen weeks. Fully online. Open enrollment — no admission threshold, no prerequisite but a self. Measured against a control group with the most extensively validated instrument in the field. Scored blind. Reported with its limits stated.
The leading longitudinal study of adult development recorded 0.55 stages over eighteen years — which breaks down to a natural pace of approximately 0.01 stages every sixteen weeks. Remarkably, this study's own control group grew exactly that amount: 0.01 stages in sixteen weeks. The intervention group grew 0.49 stages in the same interval.

Most workplace development work has failed on two axes at once. Most of it isn't deep enough — not truly developmental at all: skills and content poured into a meaning-making structure it never touches. And the rare work that does transform is coaching-intensive and executive-priced — a delivery mechanism that cannot reach a whole company. The Course was built, and tested, to be both: depth that is measured, in a form wide enough for everyone.
Complements, not competitors: The Course is the wide base that makes high-touch work land on ready ground — at the price of a textbook, not a retainer. For organizations →
This is not a promotion. It is a planned loss, budgeted from the start — because a mission to make development available to everyone is tested at exactly one place: the wallet of the person who cannot pay. If that is you, write to us and take the course. No means test, no proof of hardship, no separate track. You will simply be in it, like everyone else.
Printed at the same weight as the findings, because the limits are part of the finding.
Ego stage was measured with the Washington University Sentence Completion Test (WUSCT; Loevinger, 1976; Hy & Loevinger, 1996) — the most rigorously validated instrument in the field, and the one used by Manners et al. (2004) and Vincent et al. (2015). The WUSCT is convergent with but not identical to Kegan's Subject–Object Interview. Findings framed in Kegan's orders of mind are reported as a correspondence (Cook-Greuter, 2004; McCauley et al., 2006), not as a substitution.
Decades of research have correlated later-stage ego development with a long list of advantageous outcomes — perspective-taking, tolerance of ambiguity, principled ethical reasoning, adaptive leadership, psychological resilience. But correlation is not conferral. What the WUSCT measures is the structural complexity through which a person construes experience, not the virtues, skills, or wellbeing that may follow from it.
The course treats stage growth as a developmental capacity that affords more adequate responses to complexity — not as a ticket to them.
The present findings come from one intervention, one institution, one cohort, and one investigator. They extend Manners et al. (2004) and Vincent et al. (2015), but independent replication — particularly by teams with no stake in the course's design — is essential before the results should be treated as settled.
Our organization is governed by thirteen principles.
