Measuring what changed.
Most training reports count attendance and satisfaction because those are the two things that can be measured without the client's cooperation. Neither tells anyone whether the organisation is better at anything.

01The four levels
We agree the evaluation level before the programme, not after.
Where a return on investment figure is required, we apply the Phillips model on top of level four, with the assumptions stated on the page rather than buried in an appendix.
Two things we will not do.
Claim a result the data cannot carry
If turnover fell in the year we ran a leadership programme, the programme may have contributed. It did not cause it on its own, and a report that says otherwise is worth nothing the first time an executive asks a hard question about it.
Measure at level four without the client's data
Level four requires operational figures we do not own. Where a client cannot or will not release them, we say the evaluation stops at level three rather than constructing a number.
