Has anyone ever skipped a level?

My son has been doing 7-9 and debating skipping the next level as he is really in 5th grade and is ready for harder concepts. We did 7-9 due to handwriting issues but it has now resolved.
Debating skipping...thoughts?

I have done two years curriculum in one calendar year to catch up and that worked well for us. I didn't want to miss any important concepts by skipping a level. But, ultimately, you can do what you feel is best for your child.

Wow two years in one year! Explain how you did that.

First, there are extra days in the curriculum for wiggle room. So instead of 15 lessons for a three-week unit, there are 13 or 14. I kept doing one lesson a day which gave me about a month less of schoolwork (35 weeks of schooling in a 52 week year). I would also occasionally skip a lesson with concepts we knew well already. And I worked over a full year (instead of the usual 9 months). It is not easy but can certainly be done. A much more reasonable solution is to do three levels of curriculum over two years.

Ok we are already schooling year round. It's taking an average of 4 weeks to get a unit done plus I have to work around the college tutor class schedules/finals week etc. I have stepped in and taught a lesson here and there in her absence but sometimes it throws everyone off when she returns. He is moving faster now than he was at the beginning of last year. So maybe by the middle of this year, he can start speeding up to three weeks rather than 4 weeks or I can do the lessons and the tutor can monitor the projects and writing activities. It takes him a LONG time with lots of reminders to stay at the table. I can't wait until he can start doing the lessons independently. Three levels over two years seems a lot more reasonable.

We skipped. My 8 year old (gifted) was bumped up initially to the 9-11 and then when her sister was doing 10-12 we realized we could just do them together. Made our life much much easier. So they are now doing the same level (heading into 11-13) and she's going to be 9. We have a private tutor so we can be sure nothing was missed. We also had her do an online science program that "went quick" and was fairly easy to make sure we had no holes. Took us about 2 months to "check all the boxes off". Much easier however doing the same material and collaborating and discussing the books etc together is a lot more fun. I think we get more depth this way. If you have kids a year or two apart, you might want to consider this.
