Need to write a letter to director or principal of school

Imagine that your school or center has adopted performance assessment to measure student growth.  Your principal or director has asked you to create a letter for your students’ parents explaining performance assessment.  In your letter, you must address the following:

1. At least two reasons why using performance assessment with children is a reliable method of measuring student growth.
   
   
2. At least two typical concerns associated with performance assessment and how you will address those concerns.
   
   
3. At least two different performance assessments that you will use in the classroom and why you will use these assessments.

THEY RECOMMEND TO WRITE IN YOUR OWN WORDS.  BUT IF YOU WANT TO USE ANY OUTSIDE SOURCES IT MUST BE PROPERLY CITED IN APA FORM WITH A REFERENCE AT THE END.
