You really have to watch those teachers. Some are very sly when it comes to this matter.
My son has a love for his ReadingPlus; and would get to certificates very quick. Teacher told me during PT meetings to reduce the time my son spends on ReadingPlus bla bla bla. I listened to her and did as she advised.
One day I had the luck of volunteering with his class, and arrived early so was allowed to start lessons with the kids. Took time to look at the walls, and saw all the folks with ReadingPlus certificates, not one looked like me. I received sense quickly.
