A weighted performance measurement instrument, under document control
The organization needed to know how well teaching was actually being delivered across three branches, continuously, without relying on anyone's impression. I designed a twenty-index instrument spanning three scored domains, each index weighted one to six, totalling 1,560 points, issued and revision-controlled as a formal document.
It drew on two independent data sources that could be checked against each other: structured lesson observation, and per-lesson assessment submitted by students. Results were published as branch rankings, so every teacher could see their standing at any time rather than learning it once a year. Measurement became a live signal instead of an annual verdict.
