Spelling and Vocab certificates are the perfect way to reward learners' efforts and keep them motivated.
In your settings tab, you can choose the grade levels and the score boundary for success at each level.
You can edit the level names and change all the grade boundaries as required. The first four levels are awarded certificates. If you would like every child to receive a certificate, simply lower the boundary of the fourth level (labeled 'Satisfactory' here) as required.
