A Class 4 child answers every oral question in science, tells long, well-ordered stories and solves puzzles quickly. Yet the same child reads aloud haltingly, guesses at words and spells "was" as "saw" in one line and correctly in the next. A teacher who sees only the reading might call the child lazy or slow. A teacher who sees the whole child notices the gap between ability and reading, and that gap is the signature of a specific learning disability.

CTET asks about learning disabilities under "addressing learners from diverse backgrounds including disadvantaged and deprived" and "addressing the needs of children with learning difficulties, 'impairment' etc." Questions usually give a short description of a child and ask you to name the difficulty or choose the right teaching response.

What a learning disability is

A specific learning disability (SLD) is a neurological difference in how the brain processes information, which makes one area of learning, such as reading, writing or maths, much harder than expected for the child's age, intelligence and schooling.

Three features to remember:

  • It is specific: it affects particular skills, not overall ability. Most children with SLD have average or above-average intelligence.
  • It is not caused by poor teaching, poverty, lack of effort, poor vision or hearing, or emotional problems, though these can make it worse.
  • It is lifelong, but with the right support children learn strategies and succeed.

The RPwD Act, 2016 lists specific learning disabilities among its 21 disabilities. It describes them as a group of conditions with a deficit in processing spoken or written language, which may show as difficulty in understanding, speaking, reading, writing, spelling or doing mathematical calculations, and it names perceptual disabilities, dyslexia, dysgraphia, dyscalculia, dyspraxia and developmental aphasia. See inclusive education for the rest of the Act.

The main types

ConditionArea affectedSigns a teacher may notice
DyslexiaReading (decoding words), spellingSlow, effortful reading; guessing from the first letter; losing the place; poor spelling that varies; reversing letters or words well past the early grades; difficulty linking sounds to letters
DysgraphiaWritingVery untidy or effortful handwriting; irregular letter size and spacing; awkward pencil grip; tiring quickly; ideas far better spoken than written
DyscalculiaMathematicsWeak number sense; difficulty judging which number is bigger; counting on fingers long after classmates; confusing symbols such as + and ×; trouble with place value and telling time
DyspraxiaMotor planning and coordinationClumsiness; difficulty with buttons, scissors, catching a ball; messy written work
Developmental aphasia (dysphasia)Understanding or producing spoken languageDifficulty finding words, following instructions or forming sentences
Auditory and visual processing difficultiesMaking sense of what is heard or seen, despite normal hearing and sightMishearing similar sounds; difficulty copying from the board

ADHD (attention deficit hyperactivity disorder) is often listed alongside, but it is a separate condition that affects attention, activity level and impulse control. It is not one of the 21 disabilities named in the RPwD Act, though it often occurs together with SLD. Signs are difficulty staying on a task, acting without thinking, and restlessness that is more than normal childhood energy.

What a learning disability is not

TermMeaningHow it differs from SLD
Intellectual disabilitySignificantly below-average intellectual functioning and difficulty in everyday adaptive skills, beginning in childhoodAffects learning across all areas; in SLD, general ability is typical
Slow learnerA child who learns across subjects at a slower pace than the average, often described as having below-average but not disabled abilityNot a disability category; the child needs more time and practice across the board
Learning difficulty from circumstancesPoor schooling, language mismatch, absence, hunger, stressImproves when the cause is addressed
Sensory impairmentLow vision or hearing lossMust be ruled out first; glasses or hearing support may solve the problem

A teacher does not diagnose. The teacher notices, records observations, talks to parents and refers the child for assessment by qualified professionals.

Supporting the child

Multi-sensory teaching

Learning through several senses at once, seeing, hearing, saying and touching, builds stronger links. Examples: tracing letters in sand or on sandpaper while saying the sound; building words with letter tiles; using beads, bundles of sticks and number lines for place value. The Fernald (VAKT) method and Orton–Gillingham approach are well-known multi-sensory methods for reading.

Strategies by area

ForTry
ReadingExplicit phonics taught step by step; short daily practice; audiobooks and reading aloud to the child; larger, clearer print; a reading ruler or card to keep the place
WritingPencil grips; lined or squared paper; oral answers or dictation; typing where possible; fewer copying tasks; mind maps before writing
MathsConcrete objects before symbols; number lines; squared paper to line up digits; a multiplication table card; extra time
Everyday classBreak tasks into small steps; give instructions orally and in writing; check understanding privately; seat the child near the teacher

Attitude and assessment

  • Praise effort and progress, not only correct answers.
  • Never ask the child to read aloud in front of the class without warning.
  • Assess what the child knows, not only how well they read or write: allow oral answers, extra time or a reader or scribe where the rules permit. Boards such as CBSE provide such accommodations to certified students; check the current rules.
  • Work with parents and special educators, and keep records of what helps.

Worked classroom questions

Scenario 1

A child explains a science experiment clearly and correctly but writes only two illegible lines about it, with letters of varying sizes. The difficulty most likely is:

(a) dyslexia (b) dysgraphia (c) dyscalculia (d) intellectual disability

Best answer: (b). Understanding is good; the barrier is in writing.

Scenario 2

A Class 3 child cannot tell whether 46 or 64 is bigger and counts on fingers for 3 + 2. Reading is at grade level. The teacher should first:

(a) give extra drill of 50 sums daily
(b) observe and record the difficulties, use concrete materials and number lines, and discuss a referral with the parents
(c) tell the child to try harder
(d) exempt the child from maths

Best answer: (b). Possible signs of dyscalculia; observe, support and refer.

Scenario 3

A child with dyslexia is embarrassed when asked to read aloud. The best approach is to:

(a) make the child read aloud daily so they get used to it
(b) excuse the child from all reading
(c) give the child a chance to practise the passage privately first and offer other ways to take part
(d) seat the child at the back

Best answer: (c). It protects dignity while still building the skill.

Practice MCQs

Q1. Dyscalculia relates to difficulty in:

(a) writing (b) reading (c) mathematics (d) movement

Q2. Children with specific learning disabilities usually have:

(a) below-average intelligence
(b) a lack of motivation
(c) hearing loss
(d) average or above-average intelligence

Q3. Which condition is named in the RPwD Act as a specific learning disability?

(a) Dyspraxia (b) ADHD (c) Low vision (d) Cerebral palsy

Q4. Dysgraphia is mainly a difficulty with:

Q5. Tracing letters in sand while saying their sounds is an example of:

(a) rote learning (b) programmed learning (c) punishment (d) multi-sensory teaching

Q6. A teacher suspects a child has a learning disability. The teacher should:

(a) observe and record, talk to parents, and refer for professional assessment
(b) label the child in the register
(c) make the child repeat the year
(d) diagnose the condition and prescribe treatment

Q7. Difficulty in understanding or producing spoken language is:

(a) dyslexia (b) developmental aphasia (c) dyscalculia (d) dysgraphia

Answers

  1. (c).
  2. (d).
  3. (a). ADHD is not one of the 21 disabilities.
  4. (c).
  5. (d).
  6. (a). Teachers identify and refer; they do not diagnose.
  7. (b).

What to do next

  • Learn the six conditions in the table with one sign each.
  • Learn the list of SLD conditions the RPwD Act names.
  • Write three adaptations you would make for a child with dyslexia in your subject.
  • Revise how children think and learn, since treating errors as clues is the same skill.
