The Senior Ski and Toboggan evaluation traditionally happens once a year on the first weekend in March.  

The Ski and Toboggan evaluations are separate from each other and are conducted on the same day. Both evaluations must be registered separately on the NSP website. If you pass one, you will have three seasons to pass the other (plus Senior OEC and your electives) before the skill you passed expire and need to be evaluated again.
