Agreed. Try to collect as much tangible data as you can to support your situation. I really feel you should go with the full eval at this point to see what you are dealing with. Find out what's behind the handwriting and expression issues from a specialist. They can get you the special education plan if you need it.
I look at how stressed I was last year. The thought of repeating the process and starting over with each teacher for 11 more years makes me realize it may not be a good idea for me!
I'm not sure I have the temperment to deal with it!
I'm currently attempting to take advantage of a partial homeschool availability that our state has. This way the girls can attend school with their friends(they get a long with different age groups and we are lucky that they both like being with their same age group as well), yet spend part of their day, working at their appropriate learning level. And I don't have to put the burden on the teacher. I think it works for everyone. The girls are happy, parents feel learning needs are adressed to some point, teacher doesn't have to deal with me!
