Cecilia, This is always a tough sell because the administration does not want to spend money on things like classroom settings. You have a better chance of selling your needs to the administration if you tie the need directly to a learning deficiency. Also, for example using the dimming situation you mentioned, I would put a cost to the installation of a dimmer switch in the class. By having the cost available sometimes administrators will give the go ahead for the installation because the amount doesn't seem a lot. Then you can cost out the next thing you want. What you are doing is giving them increments rather than the total cost. Just an idea that has worked for me. Gary Dr. Gary Meers
