Query 4100Q will occur for teachers without a Teacher number (and this must be loaded for all those teachers with recognised Qualified Teacher Status and also for any others who might have a English or Welsh teacher number e.g. if on teacher pensions scheme) however this year please be aware that query 4100Q will also unfortunately occur on Unqualified Teachers too (who may have no English nor Welsh Teacher Ref Number to load)... so if the teacher is unqualified then the query is likely to remain and will need a return-level note added in Collect
