By this time, Caroline and I were actually getting quite interested to see if the new taxonomy worked as we hoped and we asked the pre-conference participants for their consent to use their data, while we repeated the activity at an internal IB conference with participants also providing consent. We now have data for about 400 items, creating links between item types and the assessment objectives and we are preparing a paper on the proof-of-concept of using a taxonomy this way.  As it is, the SIG has had lasting impact on us, and perhaps – after sharing our results – even on the digital assessment community.
