SlowcoachYou may have arrived here after searching for “borderline intellectual disability and military service.” We use that expression cautiously: borderline intellectual functioning is not the same as intellectual disability, and it does not automatically determine registration as a person with an intellectual disability.
You may have one question in mind: “Do I have to serve in the military?” Online searches produce so many conflicting answers that we checked the original Korean rules in force at the time of writing and the Military Manpower Administration's guidance directly.
To answer first: borderline intellectual functioning alone does not result in automatic exemption.
Military service assessment is not determined by one IQ number. The rules call for consideration of social and occupational functioning alongside psychiatric assessment, and the final result is determined through each person's military service assessment examination.
1. The rules have a separate entry for borderline intellectual functioning
Item 103 of Schedule 3 to Korea's Rules on Physical Examinations and Other Examinations for Military Service Assessment is titled “Borderline intellectual functioning and intellectual disability (intellectual developmental disorder).” Within it, subitem (a) sets out borderline intellectual functioning and subitem (b) separately sets out intellectual disability criteria.
Schedule 3 to the Rules on Physical Examinations and Other Examinations for Military Service Assessment contains Item 103, “Borderline intellectual functioning and intellectual disability (intellectual developmental disorder).” Its subitem (a) concerns borderline intellectual functioning.
When checking military service criteria for borderline intellectual functioning, you should therefore not apply the intellectual disability criteria or disability registration criteria unchanged. Even though the names appear together, the assessment wording distinguishes them.
2. The rules do not contain a table assigning a grade to each IQ range
Tables such as “IQ below 70 means Grade 5, and 71 to 84 means Grade 4” appear repeatedly online. But Item 103 of Schedule 3, as checked on 19 August 2026, does not present IQ ranges as a formula for assigning grades.
Instead, it states the following.
Item 103. Borderline intellectual functioning and intellectual disability (intellectual developmental disorder)
Note: Assessment shall refer to materials including standardised individually administered intelligence tests, social adaptation tests and elementary, middle and high school records, together with psychiatric assessment and other relevant information.
(a) Borderline intellectual functioning
1) Cases requiring observation for a certain period going forward: Grade 7
2) Mild: cases with mild impairment in social and occupational functioning: Grade 4
3) Moderate: cases in which a co-occurring psychiatric condition is being treated, or impairment in social and occupational functioning is marked, and these circumstances are judged to interfere with military service: Grade 5
(Translated excerpt from Schedule 3 to the Rules on Physical Examinations and Other Examinations for Military Service Assessment, as amended on 1 February 2024. These rules were in force on the date they were checked.)
The physical grade for borderline intellectual functioning is assessed through social and occupational functioning and psychiatric assessment, rather than through a single IQ number.
3. What has become mixed together in the IQ figures online?
“IQ of 70 or below” appears in the intellectual disability criteria in Schedule 1 to Korea's Enforcement Rule of the Act on Welfare of Persons with Disabilities as in force when this article was written. But that is not a table for calculating military physical grades. Disability welfare and military service assessment are systems with different purposes and procedures.
“IQ 71 to 84” is a range often used when explaining borderline intellectual functioning. These numbers are likewise not used in the military rules' Schedule 3 as a formula automatically separating Grade 4 from Grade 5.
Combining figures from different systems with military Grades 4 and 5 can produce a plausible-looking table. It should not, however, be used as a formula for predicting an individual's military assessment. For the related concepts, the earlier article below explains IQ ranges and adaptive functioning separately.

4. So which grade will I receive?
The grades listed under borderline intellectual functioning are Grade 7, Grade 4 and Grade 5.
Grade 4 concerns mild impairment in social and occupational functioning. If the final physical grade is Grade 4, the military service classification is supplementary service, and the person may be subject to a call-up as a social service agent.
Grade 5 applies when the rules' moderate criteria are met. The assessment considers whether a co-occurring psychiatric condition is being treated, or whether social and occupational impairment is marked and judged to interfere with military service. A final physical grade of 5 leads to classification in wartime labor service.
Grade 7 applies when an immediate determination is difficult and observation over a further period is needed. The person undergoes a repeat physical examination.
The borderline intellectual functioning entry in Item 103 does not itself contain Grade 6 criteria.
The Grade 6 criteria appear under severe intellectual disability in the same Item 103. They concern cases where daily life is judged to be substantially affected to the extent that assistance from another person is needed for personal care.
This explains Item 103 only. The actual final physical grade and military service classification depend on the individual's examination results, including assessments of other illnesses or physical or mental impairments. The central point is that borderline intellectual functioning alone does not automatically lead to exemption, and one IQ number does not determine the grade.
5. Check the Military Manpower Administration's official information on examinations and documents
The Military Manpower Administration uses psychological testing in military service assessment examinations to identify people requiring a detailed psychiatric examination. Where needed, additional psychological testing and psychiatric assessment follow. School records may also be consulted when assessing Item 103.
This does not justify assuming, “The Military Manpower Administration will check everything, so I don't need to prepare anything.” If you have previous intelligence test results, medical records or school documents, it is safer to check whether they need to be submitted or accessed. The Administration's guidance at the time of writing generally directed people with a history of illness to obtain a military-purpose medical certificate issued within 3 months by a designated hospital, together with relevant medical records. Exceptions and additional documents depend on the condition and treatment history, so check the examination notice and the Administration's document requirements by specialty and condition.
The principle is to submit truthful information about the current condition and treatment history. The documents are not a means of obtaining a particular grade; they help the assessing physician understand the individual's condition and functioning accurately.
A different procedure applies if a person who has already been assessed seeks a change in military service classification because an illness has worsened or a new illness has developed. Basic documents and additional material differ according to the reason for the application. For intellectual disability or borderline intellectual functioning, provisions allow a general medical certificate or a certificate for assessment of disability severity to replace a military-purpose medical certificate. Do not therefore assume that both certificates are required. Check with the relevant regional Military Manpower Administration before submitting them.
6. If you have questions about your own situation
This article explains only how the rules are set out. The final decision is made through the military service assessment examination.
For questions about your notice, treatment history or required documents, the most precise route is the Military Manpower Administration's main number, 1588-9090, or the regional office responsible for your place of residence. The main telephone line operates on weekdays from 9 a.m. to 6 p.m. If calling feels difficult, you can use the enquiries service on the Administration's website.
This article provides general information explaining official rules checked on 19 August 2026. It does not predict an individual's assessment outcome.
Laws and document requirements can change, so please check the official pages below again before your actual examination.
7. Whatever the outcome
Whether the classification is active duty, supplementary service or wartime labor service, it does not determine a person's worth.
Military service is one period of life, and the years that follow are much longer. Some people we have met have described difficulty settling into work because the pace at which they first learned tasks did not fit the way instructions were given in the workplace. This does not mean that everyone has that experience or that it explains every departure from a job.
Slowcoach is developing support that stays alongside people at that point. We are preparing an AI workplace guide that welcomes repeated questions, together with a human coach who checks in on emotional wellbeing once a week. We are aiming for a formal start in autumn 2026 and are currently meeting people individually to listen to their experiences. There is currently no charge for these consultations.
