Responsible use of Resources

One of the constants in the educational world is the idea that there is simply never enough money and the district stays in a budget crisis.  With that being understood, WHY in the world are there so many unused resources?  For example, when a district purchases a textbook, there are often optional packages and resources that make the total cost of the textbook adoption even more expensive. Those resources beyond the actual textbook itself, generally go unused.  One of the leadership standards require that educational leaders be good stewards of the resources allocated to schools yet there are not many tools or measurements in place that specifically help administrators to objectively determine if they are indeed being "good" stewards of the resources allocated to the schools.  I believe that along with the academic and school culture measurements that are made public, there should be a measure that is made known to the public in a similar fashion with regard to the use of allocated resources or funds.
To be clear, I'm not sure that such a measure doesn't already exist, but that in of itself is also a problem especially since there are very few educators that are not aware of CCRPI data and the school culture surveys.  This could help districts and schools make better decisions around allocations and quite honestly, the money that is unwisely spent on resources could be reallocated to a more worthy cause or even to teacher salaries.
