Forum topic

I have always taught a classroom forum on peripheral IV access to our new hires. They would test on the education and this would be their classroom competency. They then would be observed at bedside performing the actual insertion and this would be their bedside competency. I have been asked to stop the classroom education. I am told that they learn all this information in school and I should not have to repeat. They only need to be observed at bedside.
I need guidance or references to the need for the classroom education. The students do not know anything in reference to venous anatomy and how infusions effect these linings, vein identification, complications and how to treat, vein selection and catheter selection etc,.
