Participants are measured on their own protocol clock, at their Day 1, 30, 60 and 90. Employers are reported to on the calendar clock, once a quarter. The two are reconciled by reporting only Day 1 to Day 90 movement, within the same individuals, for those who reached Day 90 during the period. Days 30 and 60 are never reported to the employer in any form.
2.1 Enrolment is continuous. There is no fixed cohort start date. A participant's Day 1 is the date they enrol, so Day 30 falls on a different calendar date for every participant.
2.2 It follows that a "Day 30 report" to an employer cannot be produced, because no shared Day 30 exists across a population. This is a consequence of the enrolment design, not a reporting preference.
2.3 Employer reporting is therefore fixed to calendar quarters, and the measurement points are fixed to the individual. The reporting period is the container; the protocol clock is the content.
3.1 Each participant rates themselves from 1 to 10 on seven measures of their working day: output quality, decision confidence, focus and concentration, presence in meetings, energy management, recovery between demands, and perceived operational capacity.
3.2 They do so four times: at their own Day 1, Day 30, Day 60 and Day 90. Day 1 is the baseline against which all movement is measured.
3.3 The scores are self-reported. See section 9.
4.1 Three figures, once per calendar quarter, and nothing else.
| Figure | Definition | Population it describes |
|---|---|---|
| Seats occupied | Count of seats in use | All participants enrolled on the final day of the reporting period |
| Completion rate | Proportion who completed all 90 days | Only those whose Day 90 fell inside the reporting period |
| Aggregate Index movement | Mean change from Day 1 to Day 90 across the seven measures | Only those same completers |
4.2 The three figures describe three different populations. Each is labelled on the face of the report. They are not intended to reconcile to one another and should not be read as doing so.
Every movement figure is a within-person comparison. Each participant contributes a Day 1 score and a Day 90 score, and the reported movement is the mean of those individual differences.
Movement is never calculated as the difference between the average score of one group and the average score of a different group, and never as an average of whatever the most recent score happens to be across everyone enrolled.
5.1 The reason is composition. Under continuous enrolment, the mix of participants at each stage changes every quarter. A figure built on the current population would move as that mix changed, independently of any effect of the protocol, and would not be a valid measure of anything.
5.2 The matched-pair rule removes that. If the reported movement changes, it is because the participants who completed in that period moved differently, not because different people were counted.
| Case | Treatment |
|---|---|
| First reporting period | No participant has reached Day 90. Seats are reported. Completion and movement are reported as not yet available, with the date of the first expected completion. No substitute figure is offered. |
| Fewer than five completers | Seats are reported. Completion and movement are suppressed and carried into the next period in which the threshold is met. |
| Participants mid-protocol at period end | Counted in seats only. They enter the completion and movement figures in the period in which their Day 90 falls. |
| Participant leaves the organisation mid-protocol | Removed from the completion denominator. Not recorded as a non-completion. |
| Participant stops before Day 90 | Counted as a non-completion in the completion rate. Excluded from the movement figure, because no Day 90 score exists to pair with their Day 1. |
| Missing Day 30 or Day 60 score | No effect on employer reporting. Days 30 and 60 are not reported. A participant with Day 1 and Day 90 scores is a valid pair. |
| Seat unused | Reported in seats as unoccupied. Enters no other figure. |
8.1 The system holds an email address supplied by the participant, a random seat reference derived from nothing about them, and seven self-rated scores recorded up to four times. That is the complete record.
8.2 An address is necessarily held, because the protocol is delivered by email. Participants are directed to use a personal address rather than a work one, since a work address is readable by their employer's IT function. Participants are therefore anonymous to the employer, and pseudonymous to PRC Workforce. This note does not claim otherwise, and no PRC material should.
8.3 The following are absent rather than withheld, because they are not collected and no record of them exists:
8.4 Participants enrol on their own device. The employer does not assign seats to named individuals, receives no participant identifier of any kind, and is never told who enrolled.
The PRC Index is a set of seven self-report measures rated 1 to 10. It is not independently validated as a clinical outcome measure and is not presented as one. It tracks how a participant rates their own observable output across the 90-day period. Nothing further is claimed.
PRC Workforce provides non-clinical behavioural protocols. It does not constitute legal counsel, occupational health advice, or clinical medical diagnosis. This note describes reporting methodology only. It is not a contract and does not set out how personal data is handled. Contractual and data terms are issued separately.
