What Is SLD in Special Education? Understanding Dyslexia, ADHD, and More

Navigating the world of special education can sometimes feel like learning a new language. Between IEPs, 504s, and a whole host of other terms, it’s easy for parents to feel overwhelmed by an alphabet soup of acronyms. One of the most common, yet often misunderstood, is SLD.

If you’ve heard this term and wondered what it means for your child, you’re not alone. Understanding this category is the first step toward getting your child the right support. Let’s break down what SLD is, what it includes, and how it relates to common conditions like dyslexia and ADHD.

What Does SLD Stand For in Special Education?

SLD stands for Specific Learning Disability. This is a formal classification used in schools, defined under the Individuals with Disabilities Education Act (IDEA). This federal law ensures public schools serve the educational needs of students with disabilities.

Let’s look at the two parts of the term:

  • Specific: This is the key. An SLD affects a specific academic skill area. It doesn’t mean a child has a low IQ or is incapable of learning. In fact, many students with SLDs have average or even above-average intelligence. The challenge is localized to one or more areas, like reading, writing, or math.
  • Learning Disability: This refers to a challenge in how the brain takes in, processes, or expresses information. It’s a neurological difference, not a problem of laziness or lack of effort. Think of it like a radio that can tune in to every station perfectly, except for one specific frequency; the brain has a similar processing hiccup for a particular skill.

Under IDEA, an SLD is a disorder in one or more of the basic psychological processes involved in understanding or in using language, spoken or written. This can make it difficult to listen, think, speak, read, write, spell, or do mathematical calculations.

Is Dyslexia an SLD?

Yes, absolutely. Dyslexia is the most widely recognized type of Specific Learning Disability. It is a language-based learning difference that specifically impacts reading and related language skills.

For a child with dyslexia, the brain has trouble connecting letters to the sounds they make (phonological awareness), which makes decoding words, reading fluently, and spelling a significant challenge. It’s crucial to remember that dyslexia is not a vision problem; it’s a difference in how the brain processes written text.

Dyslexia is just one type of SLD. Other common examples include:

  • Dysgraphia: An SLD that affects a person’s handwriting ability and fine motor skills. A child might struggle to form letters, space words correctly, or organize their thoughts on paper.
  • Dyscalculia: An SLD that affects a person’s ability to understand, learn, and perform math and number-based operations.

Is ADHD an SLD?

This is where things get confusing, but the distinction is important. Technically, under IDEA, ADHD is not considered a Specific Learning Disability.

Instead, Attention-Deficit/Hyperactivity Disorder (ADHD) is most often classified under a different category called “Other Health Impairment” (OHI).

The OHI category is for conditions that limit a student’s strength, vitality, or alertness, including a heightened alertness to environmental stimuli, that adversely affect their educational performance. Because ADHD directly impacts a child’s ability to maintain focus and attention in a classroom, it falls squarely into the OHI category.

However, the confusion is understandable because the symptoms of ADHD (inattention, impulsivity, and hyperactivity) can make learning extremely difficult, and academic struggles can look like an SLD.

Even more importantly, SLD and ADHD often co-occur. A significant number of children with an SLD like dyslexia also have ADHD. The two are distinct conditions, but their challenges can overlap and magnify each other.

A child might struggle to decode a word because of dyslexia, and their inattentiveness from ADHD makes it even harder to apply the strategies they’ve been taught. That’s why a comprehensive evaluation is so critical to identify everything that’s going on.

How Can I Get My Child Evaluated for an SLD?

If you suspect your child has a learning difference, trust your instincts. The process for getting an evaluation can feel formal, but it’s a right you have as a parent.

  1. Document and Discuss: Start by taking notes on your specific concerns. What do you see at home? Then schedule a meeting with your child’s teacher to discuss their classroom observations.
  2. Make a Formal Request: Put your evaluation request in writing to the school’s principal or special education director. A written request creates a paper trail and legally requires the school to respond within a specific timeframe. State that you are requesting a “comprehensive evaluation for special education services.”
  3. The Evaluation Process: If the school agrees to evaluate, a team will conduct a series of assessments. This often includes psycho-educational testing, classroom observations, and input from you and their teachers. You have a right to receive a copy of this evaluation report.

What Support is Available for Children with SLDs?

Once a child is found eligible for services under the SLD category, the school will develop an Individualized Education Program (IEP). This is a legally binding document that outlines the specific support your child will receive. Support generally falls into two categories:

  • Accommodations: These are changes to the learning environment that help your child access the curriculum. They don’t change what your child learns, but how they learn it. Common examples include extended time on tests, audiobooks, speech-to-text software, preferential seating, and receiving copies of teacher notes.
  • Services and Specialized Instruction: These are direct services provided to your child to build their skills. This can include one-on-one or small group instruction with a special education teacher (often called “resource room”), speech therapy for language-based SLDs, or specialized, evidence-based reading programs like Orton-Gillingham for dyslexia.

What if the School’s Support Isn’t Enough?

Sometimes, despite an IEP being in place, you may feel your child is still struggling or not making adequate progress. This is a frustrating but common situation. You are your child’s best advocate, and you have options.

  • Request an IEP Meeting: You can request an IEP meeting at any time to discuss your concerns. Come prepared with data, work samples, your own observations, or feedback from tutors, to show why you believe the current plan isn’t working.
  • Bring an Advocate: Consider bringing a professional educational advocate or consultant to the meeting. They know the law and can help you communicate your child’s needs effectively.
  • Seek Outside Support: Don’t wait for the school system to catch up. External support, like specialized one-on-one tutoring, can fill the gaps while you advocate for better services in school. This ensures your child doesn’t lose valuable time and can start building skills and confidence right away.

The Importance of the Right Support

At the end of the day, the label, whether it’s SLD or OHI, is less important than understanding your child’s unique learning profile. These categories exist to help schools provide the right services and accommodations. What truly matters is identifying your child’s specific strengths and challenges, so you can give them the tools they need to succeed.

If you’re reading this because you see your child struggling, trust your instincts. Recognizing the signs is the first step on a journey toward empowerment.
