How long do the online training courses go for?

The free online foster parent courses each vary in length, however, on average the majority of them go for 1 hour.

There are some shorter courses of 30 minutes as well.

For each course included, it is clearly noted how long it goes for, and the certificate you receive at the end of the course mentions  how many training hour credits the course is valid for, based on the length of the course.
