The latest reading age was assessed at school by a PROBE. I think we have different tests here from most of you. This one claims to assess overall fluency through speed, hesitations, omissions, insertions and dependence and reading comprehension through questions that cover literal, inference, vocabulary, evaluation, re-organisation and reaction. That's where I've got 13 from. His reading age was 12.4 on the WIAT-II when he had just turned five. So I figure if I'm aiming for somewhere round thirteen it should be fine.
We already have one of the maths ones. We just had to have a bit of a guess and got third grade because we read somewhere that since the books are aimed at gifted students it was fine just to go for the grade they would be in if they hadn't been accelerated. So we did and it was too easy, but he enjoyed it anyway as a fun activity book.
