Letter Sounds-Long and Short Vowel Sounds
If you were wondering does the student need to give both long and short vowel sounds or either one or the other to be correct, the answer is you make the call. What you decide should be consistent with your instruction.
To be most valid, the assessments should be administered and scored with the same expectations as what is being taught. If you allow them to make certain sounds in their learning process then please do so when administering our measures.
