he's always getting F's and D's and he can't pay attention 2 lng I think he has adhd.

Have these problems just started, or was your son always having difficulty in school?

Have you ever mentioned your concerns to his pediatrician, and had him evaluated for ADHD? If not, that's the first person to talk to, because ADHD is a medical condition, and while school people can tell you that they think he has attentional problems, they can't diagnose it.

Make an appointment with the school. Request that your son be evaluated by the child study team - educational and psychological testing. Specifically address his inability to stay focused and stay on task.
This testing has to provided at no cost to you. Is your son struggling with one particular subject or is he having difficult in all areas? At home, is he able to follow directions? Is he disorganized? Does he forget things? It would be really helpful for you to record your observations. Have you had a conference with his teachers, and have they expressed any concerns in these areas? Record all this information so when you take you son in to see his doctor you will be well informed as to the extent of your son's difficulties.
Only a doctor can diagnosis if your child is ADD. The doctor can discuss with you the appropriate interventions for your child.
Keep us posted!

It could be ADHD but it can also be Irlen Scotopic Sensitivity (the eyes ability to focus and discern words). It might be psychological too. I'd hit this 2 prong. Contact the school diagnostician to have him tested for a learning disability. Contact your pediatrician to have him tested for any medical - neurological diagnosis.

My daughter's ADHD was misdiagnosed. Initially the school advised it was ADHD in 3rd grade, but in 9th grade when there was lack of progress (despite the diagnostician annually telling me she was okay), I went back to her high school and asked why she wasn't able to read and why she still couldn't focus. They did a completely new workup and found she had Irlen Scotopic Sensitivity. The new tinted lenses did the track and like miraculously she was able to read the words in front of her and her grades soared.

yea.... but he's always actin rlly weird 2 thanks 4 the advice

DEFINITELY GET HIM TO HIS PRIMARY CARE PROVIDER TO BE EVALUATED FOR A PLETHORA OF CONDITIONS, NOT JUST adhd BUT DEPRESSION TOO. ....ALSO, HAVE YOUR PRIMARY CARE PROVIDER WRITE A RECOMMENDATION FOR COMPREHENSIVE TESTING TO SEE IF AN iep MAY OR 504 MAY BE APPROPRIATE IN PROVIDING EXTRA ACADEMIC SUPPORTS. YOU MUST ALSO SUBMIT SUCH REQUEST BUT KEEP A COPY OF THIS AS THEY CAN BECOME MISPLACED DUE TO THE VOLUME OF CHILDREN THEY SERVE. HAVE ANY FAMILY MEMBERS OR PETS OR FRIENDS PASSED AWAY RECENTLY? HAS THERE BEEN A MOVE?
HE NEEDS TO ALSO BE EVALUATED BY HIS OPTOMETRIST TO RULE OUT ANY VISION PATHOLOGY. ALSO, HE MAY NEED TO HAVE AN OCCUPATIONAL THERAPY EVALUATION FOR DYSGRAPHIA WHICH IS NOT DONE ROUTINELY HERE IN THE 259 SCHOOL DISTRICT AND CAN AND IS, MANY MANY TIMES BE ASSUMED TO BE OPPOSITIONAL BEHAVIOR INSTEAD OF A MOTOR PLANNING ISSUE WHICH IS A TRUE MEDICAL PROBLEM.
YOU CAN ASK YOUR CHILD'S TEACHERS TO COMPLETE WEEKLY REPORTS SUCH AS THE SNAP IV (WHICH CAN BE FOUND ON THE INTERNET-LENGTHY BUT GIVES EXCELLENT DATA FOR A TRUE CLINICAL PICTURE). THERE IS ALSO A SCORING PAGE FOR THE SNAP IV AND REALLY HELPS YOU BE ABLE TO SEE A TREND OR TRENDS IN WHATEVER DIRECTION IF THERE ARE ANY. THIS, OF COURSE, HELPS TO TAILOR MORE SPECIFIC HELPFUL INTERVENTIONS FOR SUCCESS OF OUR CHILDREN. GOOD LUCK

It is the hormones and the fact that he is growing. It is a very stressful time for a kid, phycally and psycologically.
Give him a break. Spend time outdoors, take a walk with him, go out for lunch to his favourite place and make him feel comfortable with himself and his environment. Try to connect with him so he can communicate to you any concerns he has. Buy him a book about becoming a teenager. Learn about preteens and their needs.
