Concept:Operation Blackboard is an educational scheme that was introduced as a part of the National Policy on Education (NPE) 1986 to improve infrastructure and human resources in primary schools.Explanation:The National Policy on Education (NPE) was announced in 1986 by the Indian government. One of its key initiatives was "Operation Blackboard", launched in 1987‑88. The scheme aimed to provide minimum essential facilities to all primary schools, such as at least one classroom per teacher, two teachers per school, separate toilets, and appropriate teaching‑learning materials. This clearly links the scheme directly to NPE 1986. Other options (Kothari Commission, NCF 2000, NCF 2005) are not associated with Operation Blackboard.Additional details about the other commissions are given in the table below:
