Does My Child Have a Learning Disability?

Each of these age divisions also has subtopics with very helpful information.

Pre-K to Grade 2

Pre-kindergarten through the second grade is a crucial time for parents and educators to recognize early warning signs of learning disabilities (LD). Features of LD may be hard to spot during this time, however, as children can mask their struggles by playing up strengths and hiding weaknesses.

Grades 3 to 8

During grades three through eight, children are no longer learning how to read, but rather are reading to learn. This is a major turning point in education—one that has big implications for children with reading-related learning disabilities, like dyslexia. Throughout this time, children are figuring out how they learn, and parents are figuring out how to support their child’s learning.

Grades 9 to 12 (High School)

Once high school comes around, it’s important that students know how to take charge of their learning disability (LD) and are able to articulate what they need in order to succeed. High school issues are tough enough—competition, planning for the future, and raging hormones, to name a few—which is why it's important that teens know how to deal with LD-related obstacles.

College & Adult

Living with a learning disability (LD) is no easy task. Throughout your life, your LD accompanies you everywhere—to the workplace, the supermarket, the bowling alley…it's always there. Adults need to understand how to manage their LD and the risks and advantages of disclosing their LD status in college, at work, and beyond.
