The method of giving a spelling test remains the same regardless of the age of the student:

1.  Say the test word.  e.g. “road”
   
2.  Repeat the word in a sentence. e.g. “We have a long road to travel down.” 
    
3. Repeat the word “road”, before the student writes it.

Make sure students Name and Date their test and encourage the students to have a go at each word until it is clear that they have gone well past their level.
Always give lots of encouragement, without instruction and conclude by saying," good effort".
