Disability Assessment Guidelines
On this page
Direct answer
"Benchmark disability" is the phrase that unlocks every entitlement: under the Rights of Persons with Disabilities Act 2016 — in force from April 2017, replacing the 1995 Act — a person with a specified disability certified at 40% or more becomes eligible for reservation (4% in government posts, 5% in higher education), free education between 6 and 18 years, and scheme benefits. The Act recognises 21 specified disabilities (up from 7 in the 1995 Act), including intellectual disability, autism, thalassaemia, haemophilia, acid-attack victims and Parkinson's disease. Assessment follows the Guidelines for Evaluation of Specified Disabilities notified in 2018, which prescribe the test, the tool and the percentage formula for each condition — for intellectual disability, IQ bands map to certification percentages (mild, IQ 50-69, commonly certified at 50%; moderate 35-49 at 75%; severe 20-34 at 90%; profound below 20 at 100%). Certification is issued by a medical board or designated medical authority using the standard format, with permanent disabilities certified as lifelong and variable conditions flagged for review.
What you must remember
- Legal spine: RPwD Act 2016 (force 19 April 2017), replacing the Persons with Disabilities Act 1995.
- 21 specified disabilities: the 1995 list of 7 expanded to 21 — adding intellectual disability, autism, specific learning disability, acid-attack victims, Parkinson's, thalassaemia, haemophilia and others.
- Benchmark disability: 40% or more, certified by the competent authority — the single number the chapter hangs on.
- 2018 guidelines: the notified evaluation guidelines give each disability its objective test and percentage — intellectual disability by IQ and adaptive behaviour (mild 50-69, moderate 35-49, severe 20-34, profound below 20); blindness by presenting visual acuity below 3/60 or visual field under 10 degrees.
- Reservation entitlements: 4% in government employment (identified posts) and 5% in government higher-education institutions for benchmark-disability candidates.
- Other entitlements: free education 6-18 years in neighbourhood or special schools, legal capacity with reasonable accommodation, non-discrimination mandates.
- Certification machinery: medical board or notified medical authority with condition-relevant specialists; certificates lifelong for permanent conditions, reviewable for variable ones.
- Institutional ecosystem: Accessible India Campaign (Sugamya Bharat, 3 December 2015) for built environment, transport and ICT; ADIP scheme for assistive devices; chief and state commissioners.
How a percentage is fixed: the certification pathway
A seven-year-old's school flags learning difficulty; the district medical board's clinical psychologist administers an IQ test (an Indian-adapted scale such as Malin's) and assesses adaptive behaviour. IQ 42 with significant adaptive impairment places the child in the moderate band; per the 2018 guidelines the certificate states intellectual disability, moderate, 75%. The guidelines build in review during developmental years, so the board may call the child back. With that certificate the family unlocks the entitlement stack: reservation norms, free education, travel concessions, ADIP aids, and state disability pension eligibility.
A man with best-corrected acuity below 3/60 in the better eye qualifies as blind; low-vision grading runs from 40% for milder impairment to 100% for no light perception, with field loss under 10 degrees certified at the blindness end. Haemophilia is graded on bleeding frequency and factor levels; acid-attack victims on facial and functional involvement. The design principle examiners want named: percentage certification converts a clinical diagnosis into an administrative key, so the guidelines pursue objective, repeatable criteria rather than descriptive labels. Two safeguards follow — certification at the nearby district board, and appeal through the designated authority hierarchy.
The 40 per cent line
Numbers: 2016 Act in force 2017, 21 disabilities, 40% benchmark, 4% job and 5% education reservation, the 1995 Act's 7 disabilities as contrast. Definitions: blindness at presenting visual acuity below 3/60 or field under 10 degrees; intellectual disability bands by IQ (50-69 mild, 35-49 moderate, 20-34 severe, below 20 profound) with their commonly quoted certification percentages of 50, 75, 90 and 100. Concept traps: "disability" versus "benchmark disability" (40% or more) — stems swap them; certification is by medical board, not any single treating doctor; and the guidelines are 2018, the Act 2016. Current-affairs hooks: Accessible India Campaign from 3 December 2015, and the RPwD Act's rights-based shift from the 1995 welfare model.
Frequently asked questions
What is benchmark disability under the RPwD Act 2016?
A specified disability certified at 40% or more by the competent medical authority — the threshold unlocking reservation, free education and welfare entitlements.
How many specified disabilities does the 2016 Act recognise and what did it add?
Twenty-one, up from seven in the 1995 Act, adding intellectual disability, autism, specific learning disability, acid-attack victims, thalassaemia, haemophilia and Parkinson's disease among others.
How is intellectual disability percentage certified per the 2018 guidelines?
By IQ band with adaptive-behaviour assessment — mild (IQ 50-69) commonly 50%, moderate (35-49) 75%, severe (20-34) 90% and profound (below 20) 100%, issued by a medical board.
What reservations flow from benchmark disability certification?
Four per cent in identified government posts and five per cent in government higher-education institutions, alongside free education from 6 to 18 years.
Who certifies disability and for how long is a certificate valid?
A medical board or notified medical authority with condition-relevant specialists; permanent disabilities are certified lifelong, while variable conditions and childhood intellectual disability carry review intervals.
