My 14 year old has been failing or close to failing school since 5th grade. She is an intelligent, bright student with no known learning disabilties. She completes work but doesn't turn it in. We have taken away her cell phone, computer use and anything that means something to her, and even this doesn't work. Anyone out there have any info? She is now failing every one of her 9th grade classes. She doesn't seem depressed or anything like that either.
