Trunky,
more interestingly, for (certain factors) which were common to all pay bands (mto 1--> mto 5) where the same terminology was used in the JD/person spec, we saw variatons from level 1 to level 4 in our 'matched' profiles
Perhaps this could be due to the fact that on different bands certain factors have different weightings hence scoring potential? For lower bands the maximum weighting, therefore level that can be attained for some of the factors, appears to be "capped" as far as I've looked into it.
So what on the face of it, in a job description, appears to be the same terminology for a factor will obtain a lower level and score for an MTO1 than an MTO4 when two hypohetical individuals are initially matched onto these profiles (initial matching is based on the knowledge/experience and freedom to act factors in the job specification/job description/organisation chart, primarily, I believe).
