I think your first point needs to be more about how schools are focusing more on common core subjects like reading and math because those are two of the main subjects tested on the state assessment test. Test scores help determine how a school is doing and so schools focus more on that. Because of this, performing arts classes like drama, music, and dance are being neglected or removed completely.
Then go into point 2 about how this one teacher saw this happening and decided to do something about it so she created an after school creative arts program to give kids a chance to express themselves creatively.
Point 3 is about how she wanted anyone to be able to participate and so she made it free to attend. She also needed lots of volunteers to help her.
Point 4 can then be about the dedication shown not only by Mrs. Nii, but also all of her other teacher and parent volunteers.
Point 5 can then wrap it up by saying that while she loves to dance, dance it not her favorite part. Her favorite part is seeing her children grow and flourish through the creative arts.
Your points are close to this but this just cleans it up a little. Now use these points to rearrange your sound bites better for your story.
