The NSTA has developed a success tracker, dashboard and methodology to allow impact to be quantified (relative to what would have happened in the absence of support or intervention).

It is intended that the data will be updated on a regular basis.  It is noted that the data is continually reviewed and may be subject to minor amendment following such review.
