We currently have four levels of subscription:
Up to 250 assigned quiz attempts per month. This is the tier every teacher is automatically assigned when they join Yacapaca. 250 attempts/month is approximately what you need to run weekly tests with one class of 30 kids. It is permanently available and not a trial period, so if this suits your needs, you are very welcome to continue using Yacapaca forever, for free.
Up to 500 assigned quiz attempts per month, over and above the free tier, i.e. 750 in total. Sufficient for light but regular usage across several classes.
Up to 7 teachers share 7000 assigned quiz attempts per month. A typical usage pattern is to run a major termly test across an entire cohort, with lighter usage in other months. With this tier, the HoD will often set up to be able to overview and analyse assignments set by all teachers in the department.
Whole school subscription
Unrestricted usage for all your teachers and students. If you want to banish restriction anxiety and encourage other departments to experiment with online assessment, this is a hugely cost-effective solution.
