I think the common exception words are generally the ‘tricky’ hfw of old and that there is much overlap, if you compare the lists.
Spelling tests generally are a subject for debate, but dyslexics often fare better with words they have been taught are tricky rather than (more often than not) selecting the wrong phonic strategy for decodable words.
There is some need to know if children can spell them to secure Standard at both year 1 and year 2. At least, it’s there on Pivats milestones 1 and 2. I would suggest using handheld spelling machines or similar ipad apps as standard to support dyslexics as this is the strategy many adult dyslexics progress on to (spell checker, dictionary etc) is a reasonable adjustment to making a best fit decision.
