Primary Agricultural Credit Societies (PACS) are village-level cooperative financial institutions that form the grassroots of India's cooperative credit system. There are over 3 lakh PACS spread across India's gram panchayats, serving approximately 13 crore farmer members. PACS provide short-term crop loans (Kisan Credit Cards), medium-term loans for farm equipment, consumer goods on credit to members, and savings services. They also function as service cooperatives, distributing fertilizers, seeds, and agricultural inputs to members at controlled prices. NABARD provides refinance through the state cooperative banking chain (NABARD → SCB → DCCB → PACS) to support agricultural lending operations.

The PACS Secretary is the key functionary of a Primary Agricultural Credit Society, responsible for day-to-day operations including maintaining member registers, processing loan applications from farmers, maintaining cashbooks and ledgers, organizing general body meetings, ensuring proper election procedures, filing annual returns with the Registrar of Cooperative Societies, coordinating with the District Central Cooperative Bank for refinance, and maintaining crop loan accounts. The Secretary is also responsible for distributing agricultural inputs (fertilizer, seeds) if the PACS runs a distribution function. With NABARD's computerization program, PACS Secretaries now also manage digital KCC disbursements, online loan applications, and e-SHAKTI data maintenance.

NABARD launched a comprehensive PACS computerization program to modernize 63,000+ viable PACS across India with a Central Government budget of Rs. 2,516 crore. The program involves developing common accounting software (CAS) that works across states, training PACS staff in digital operations, connecting PACS to Core Banking Solution (CBS) of DCCBs, enabling digital KCC loan disbursement and repayment, and creating the e-SHAKTI platform for member digitization. Computerized PACS can offer banking correspondent services, CSC (Common Service Centre) facilities, and government scheme delivery. This modernization makes PACS Secretaries responsible for both traditional cooperative management and digital financial services.

PACS Secretary exam tests basic accounting relevant to cooperative society operations: maintaining cashbooks, ledgers, day books, and balance sheets; principles of cooperative accounting including member share capital, reserve funds, and patronage dividend calculation; annual accounts preparation under cooperative audit guidelines; loan account maintenance with principal, interest, and overdue tracking; stock register maintenance for input distribution; and basic financial statement analysis. The cooperative audit class system (where societies are graded A to D based on financial health) requires understanding of what auditors look for in PACS accounts. Candidates with a commerce background have a natural advantage in this section.

Agriculture section covers basic crop science for major crops grown in the state — kharif crops (rice, maize, soybean, cotton), rabi crops (wheat, mustard, chickpea), and horticultural crops. Soil types, irrigation methods, and crop protection practices are tested. Government schemes for farmers including PM-KISAN, Pradhan Mantri Fasal Bima Yojana (PMFBY), Soil Health Card scheme, and e-NAM digital mandi are important. Agricultural credit concepts including KCC mechanics, interest subvention scheme, and crop loan norms set by NABARD are regularly asked. State-specific agricultural programs and major crops of the region where the PACS operates are also important.
