The Right to Education (RTE) was made a Fundamental Right by the 86th Constitutional Amendment Act, 2002. This amendment inserted Article 21A into the Constitution of India.
• Article 21A guarantees free and compulsory education.
• It applies to children between the ages of 6 and 14 years.
• The Right of Children to Free and Compulsory Education (RTE) Act, 2009, came into force on 1 April 2010.
Step 1: Understand Article 21A.
Article 21A states that:

\[
\boxed{\text{86th Constitutional Amendment Act, 2002}}
