Explanation:

Only statements 2&3 are correct.

• PARAKH has been set up as the organisation under NCERT. 

• It will work on bringing the school boards across the States and the Union Territories on a common platform. 

• As a first step, a workshop on school assessments, examination practices and equivalence of boards across the country was organised by the Ministry of Education and PARAKH in New Delhi. 

• PARAKH will act as a common platform for interaction of all concerned stakeholders in order to develop a holistic approach that ensures a fair assessment system which promotes equity in performance and equivalence in assessment of students.

Hence option 3rd is correct.
