Both AAO (Assistant Audit/Accounts Officer) and JSO (Junior Statistical Officer) are recruited through the single SSC CGL (Combined Graduate Level) exam cycle — not as standalone exams — differentiated at the Tier 2 stage by which optional paper a candidate takes.

⚡ Quick Answer (At a Glance)

Both AAO and JSO are posts within SSC CGL, not separate standalone exams
AAO: Bachelor's degree, age 18-30 (as on 1 Aug 2026 per one source); Tier 2 adds a Finance & Economics paper
JSO: Bachelor's with 60% Maths at Class 12 OR Statistics as a graduation subject, age 18-32; Tier 2 adds a Statistics paper
Tier 1 (common): 100 Q/200 marks/60 min, 0.5 negative marking
*Several exact figures (AAO Tier 2 Paper III status, JSO Paper 2 total marks) directly conflict across sources — verify before publishing

AAO और JSO दोनों SSC CGL के अंतर्गत पद हैं, अलग परीक्षाएँ नहीं
AAO: स्नातक डिग्री, आयु 18-30; टियर 2 में फाइनेंस व इकोनॉमिक्स पेपर जुड़ता है
JSO: स्नातक + 12वीं में 60% गणित OR स्नातक में सांख्यिकी विषय, आयु 18-32
टियर 1 (सामान्य): 100 प्रश्न/200 अंक/60 मिनट, 0.5 नकारात्मक अंकन
*कुछ आँकड़े स्रोतों में परस्पर विरोधाभासी — प्रकाशन से पहले पुष्टि करें

📢 Direct source conflicts found — verify before publishing

Sources disagree on whether a "Paper III" was introduced or removed for AAO in the 2026 pattern, and on JSO Paper 2's total marks (100Q/200 marks vs. 300 marks cited elsewhere). Do not publish either claim without checking the actual SSC CGL 2026 notification PDF directly from ssc.gov.in.

Frequently Asked Questions

Are AAO and JSO separate exams?

No — both are specific posts filled through the single SSC CGL exam cycle, differentiated at the Tier 2 stage by an additional Finance & Economics paper (AAO) or Statistics paper (JSO).

What is the eligibility for JSO?

A Bachelor's degree in any subject with at least 60% marks in Mathematics at Class 12 level, OR a Bachelor's degree with Statistics as one of the graduation subjects.

Is there negative marking?

Tier 1 has confirmed 0.5-mark negative marking. Tier 2 negative-marking figures are reported inconsistently across sources — verify before relying on a specific number.

क्या AAO और JSO अलग परीक्षाएँ हैं?

नहीं — दोनों एक ही SSC CGL परीक्षा चक्र के अंतर्गत पद हैं, टियर 2 चरण में अतिरिक्त पेपर (AAO हेतु फाइनेंस, JSO हेतु सांख्यिकी) से अलग होते हैं।

JSO की पात्रता क्या है?

किसी भी विषय में स्नातक + 12वीं में गणित में न्यूनतम 60% अंक, या सांख्यिकी विषय के साथ स्नातक।

Sources

SSC official site

The AAO/JSO-via-CGL structure, Tier 1 pattern, and JSO Statistics syllabus are reasonably well-corroborated across independent portals. Several figures directly conflict across sources (noted above) and the official ssc.gov.in notification PDF could not be accessed in this research pass — every numeric claim here needs primary-source verification before publishing.
