Sounds like you are on a journey, not knowing much of the childs history, I can only tell you what I have known in my child with similar issues. In 2nd grade my son began to show signs of short term memory issues in reading among very sloppy and slow writing. long and short of it he was also tested in school. In 2nd grade they will not say a child has a "LD" officially, just intervention is needed. If you have suspicions, you are probably correct to act on them in my experience the parent knows the child, and sees the struggle more. Schools will also tell you they are not qualified to "diagnose" which leaves a parent wondering what is going on. In my child's life we chose to see a person to "diagnose" because that is how I function, I NEED to know what is going on to move ahead. So we made an appointment with neuropshycologist (sp?) to diagnose what I suspected as dyslexia. He agreed and we have been reevaluated every 2 years (for our IEP) by school now, and every 4 by him. My son is now 17, and has been extremely successful in school, mostly A's and B's. My best advice is to be overly involved in what the school is doing with your child-(they do not always like this), understand it all, question and support their efforts, and know what is going on. Support the child with positive praise and examples, not just nice work, but "you got that bc of how you think differently, show them their other outstanding qualities, school is so pen and paper, and we humans do not live in only pen and paper everyday, we have relationships, and friendships bc of our other "good qualities" like sensitive hearts, good personalities, being a good listener etc.! "learning differently" can seem hard for a child, especially in 2nd grade, but I always explained it this way, it can be a gift!! In a dyslexic mind they are problem solvers instead of going more of a straight forward way, they consider alternate ways. I am dyslexic and can pack our car better than any one in our family for a trip. BC I see the puzzle before i pack it! There are SOOO many LD stars, scientist and professionals! Let the child know you are fostering their exceptional way of learning, and they will be successful. It is VERY hard in the young years, I have no desire to repeat them with my son, however it has fostered in him perseverance, detail work, and work ethic, he has had to work VERY hard in the past up to 3 hours daily with my help in JR. high in homework. There is no sugar coating the hard work. There are resources like crazy now that I wish we had then, I will list some of them at the end. When the school says the have enough for intervention, that means they suspect his IQ is usually higher than what the child can out put with pen and paper, that should be encouraging, not daunting. My son was told his vocabulary this year in HS is basically off the chart and has exceptional vocabulary skills, however he can not write the word, nor read it quickly, or write a long engaging story, but he can tell it verbally. That said he can keep up audibly with stories, and lectures. Verbal instructions, and directions, that is a different story bc they need "holding memory" which he struggles in.
I explained it to my son in 2nd and 3rd grade, like this; that his brain is full of workers, each at a desk doing a job, but on some days the workers don't all show up! Work gets slower, sometimes they file the files in the other cabinet, and another worker has to look longer to find the file when his brain is asking for the file... thats all! It had nothing to do with how "smart" he was. So be patient with your workers, and realize it is in the file cabinet!! (his brain), it just takes extra time to find it! He liked that analogy, he grasped it. So any thing encouraging like that should help your child be proud of who they are. My son to this day jokes with his friends that "even though they are not dyslexic it is ok", "he will solve all their problems", or in light comedy will say to almost any comment they make " are you picking on my bc I am dyslexic?" to which they get a laugh! They have been supportive too in helping read things if he needs it. He became "safe" with his friends and not afraid to ask for help-which is a key point.
To answer are they pulled out constantly, yes they can be, but not forever. My son has a study hall with a tutor now, and takes tests with a reader if needed, that is all, but he did leave class frequently in elementary grades, He had partner reading, and IEP every year, and I met with his teacher every year to "clue them in" you will be surprised at how many teachers are not equipped and need to be clued in.
Positive examples of successful adults: Einstien, Charles Schwab (who has a great site for LD kids), Patrick Depsty-actor Greys anatomy-severe LD, Tom Cruise and many many more who say LD made them successful. ADD-the KINKOS inventor, Airline founders I forgot which, successful bc of ADD. These people used their "difference" to forge new ground not comply, and not complying to the norm is always difficult.
Here are my loved resources:
Book: A parents guide to Dyslexia
School help: Learning Ally-voice recorded books and TEXT books.
Kindle fire: Emergent reading books, audio and visual cues
These tools help them "keep up" and should be allowed in school.
I could sit and talk about this forever, but I will end now bc I have gone way beyond what I intended...
Please ask me any questions if you need answers and I can share what I have experience with and just encourage where I do not. :)
Be encouraged these younger years are difficult, but the learning (paper reading and pen) gap does close more over time with work, I cried many a nights and days worrying about my LD son, and he will be fine I have determined now. Support is key for you as a parent!
best of luck! I will look forward to seeing what transpires in this journey.
*one last thing... Dyslexia is more than reading, writing, it has to do with memory, processing, basic ordering of ideas in daily life, and if what you said about knowing the answers, and reading for him and he fully understands, I would seriously look to this for some starting solutions. *studies say that if you can begin to train the brain as it is developing new pathways will "grow" as the child develops, so early intervention is recommended. (that is what i read and it spurred me on to really work to make a difference for him)
