I agree with everything the last person said about getting tested. Your situation sounds EXACTLY like ours. My oldest son ended up being diagnosed with a mild ADHD...basically boils down to organizational issues, time management, distraction and the biggest one...testing issues.  We spent our own money and got professional advice from a very qualified physchologist. I knew for years that my 'out side of the box' creative and well liked son had some problems focussing on what others thought were important. Although he could multitask his phone, computer, friends and social life like no one else, has many amazing talents (sk8 boarding, music)...and even kept a good position in school for many years with his grades. BUT...big but...it was like pulling teeth to get him to get his homework done at home, he couldn't remember things at the end of the day and we often found ourselves going back to the school for something forgotten and despite a good week of studying...he fails almost every test. He is now in grade 10 and we have made sacrifices to send him to a bigger and better school with a great LSC system.  The last 3 years was a right off in his old school as they did not have a clue what to do with him and kept telling us to medicate him and he slowly lost all self confidence as the teachers couldn't deal with accommodations and most of his teachers were not up to working with his family and even refused to communicate.  Fortunately, his new school is positive and he is now turning things around and has gained a great attitude for his education in the last 3 months he has been there. Its been a great noted change already.  Unfortunately, he is behind by 3 years due to the lack of support and understanding he had at his old school. In grade 3 he tested EXCELLENCE on all his PAT tests, grade 6 the was a noted drop and an increase in focus and testing issues and they really tried at that school. In his junior high school, his grade 9 PATs results were alarmingly low....we did try medication for 2 years...(several types and doses)...along with other natural things like vitamins and music, message, etc....the meds were a disaster and I would never reccommend it to any one thinking about going that route. My son became depressed and lost his natural self. We took a holiday and forgot the meds and never looked back....

About your question....having them diagnosed or at least tested can open up options for your daughter if there is more of a learning issue. I would never call adhd a disability.. i think of adhd as more of a character trait. My son is a cool kid that write music lyrics everyday and has so many friends. Even though he does not fit into a well constructed box at school...I feel he will develope his own tools that will benefit him.   If you can find a school that supports indiviuality...then even better. The sad part to all this, is that there are schools that don't understand or have the funding. My son still struggles with extreme testing issues and although he is working very hard and learning what tools work for him , and has a very supportive school and family....I am coming to terms with the fact that he may not get through school without failing some highschool courses. He has a reader to help him stay focussed during tests and I was going to look into getting him a scribe...even though his writing skills are not an issue.....he just can not seem to overcome test issues. I do not know where else to go with this....except to let the chips fall where they may and just continue to support him. Even though he has everything there for him now and is trying very hard...testing may not ever be something he overcomes?

As a teacher, I can share some frustrating news with you: Spanish is not easy.  Think about it, your daughter has probably been speaking English since she was a toddler, yet she's still learning English at school.  A lot of conjugation and memorization takes place in Spanish classes and my students used to really struggle with it.  The only way I figured out how to make it applicable to them so it would "stick" was with a (cheap!) CD with the level 1 Spanish verbs and vocab on it.  I used studytunes.org which was a God send for teens, but others such as songforteaching have good "little kid" songs.  One of those options would be better and much less expensive than a tutor.  Good luck!

Not an answer but wondering if you came up with any solutions? We are going through the same thing right now. Daughter (Soph) studies for hours and still fails tests. We had eyes checked. She wears contacts but found she needs reading glasses too. Going to a learning center for testing. Not sure what's going on..

Having taught school for 30+ years, I feel comfortable saying that you describe a child who needs help.  Get her tested!  Even if you need to spend your own money, if you use a licensed LDTC (Learning Disability Teacher/Consultant) the school district will be required to accept the findings and implement the suggestions included in the final report.  Insist that the tester be and LDTC or a child psychologist who does this type of testing.

Years ago, we tested a child for similar symptoms - it ended up that he, as an 11th grader in a great district, had never learned to read!  He could not decode.  We worked with him all year and he succeeded in elevating his reading scores to normal levels.  

An advantage to having a student tested privately, is that you choose who you tell about the results.  Today, there is little stigma attached to an LD diagnosis.  I even like to refer to them as Learning Differences, not Disabilities.

Have you thought about online help?  Students with learning differences do well on line - IF - there is a teacher on the other end whom the student can see and hear.  By wearing headsets, students are able to focus on just the teacher and the material being presented because all extraneous noise is eliminated.

Good luck!  Your child is lucky to have you as a concerned parent.
