Benefits of Certification

Rs.3,499 /-

Vskills has developed a new strategic framework for Skill Development for early school leavers and existing workers, especially in the unorganized sector to improve their employability called Trade Employable Skills (TES).

Trade Employable Skills does effective assessment and certification of candidates in different trade disciplines like Electrical, Electronics, Agriculture, Chemical, Automobile, IT, etc to make them job ready.

Why should one take this certification?

To demonstrate clear understanding and practical aspects and to get a visible recognition for this knowledge.
