I'll usually give a reassessment at the end of the marking period on everything we've worked on. It's a fairly long reassessment that everyone takes to give them one last chance to bring up anything they've been working on. Since scores can't move down a kid down, a kid that got a 5 weeks ago doesn't need to do the topics they've already mastered.
So something I'm thinking about is changing up the 5 policy a bit. I'm thinking that two 4's will still raise them to a 5, but the only skill quiz eligible for 5's will be the last one. This way, it gets rid of the "after some time" part. Any kid that ends up with a 5 demonstrated that they learned the skill and remembered it until the end of the marking period, not just a week or so. I think it might encourage kids to brush up on all their skills at the end of each marking period, hopefully increasing their retention a bit.
I worry though that it might be a bit overwhelming to have to review every single topic instead of letting them just focus in on their areas of weakness, but I feel like if they're already scored a 4 then the review process should be much shorter- maybe just a problem or two to refresh their memory.
So I'm curious to know if anyone has tried anything like this or has any thoughts that maybe haven't crossed my mind?
