    • TPRAWKS 2014 (Exclusively for 4E & 5NA)
      17 - 19 November 2014

      Temasek Polytechnic



      Dear Parents,

      Are you overwhelmed by the many post-secondary education opportunities available for your child?

      While we could extol the benefits of a polytechnic education – that it nurtures independent learning, gives opportunities for your child to develop character and leadership skills, and prepares them for careers in a global economy– you might agree that it's better if they can experience it for themselves.

      They can do so through TPRAWKS, a three-day on-campus event that encompasses workshops, team bonding events and loads of exciting games and activities.

      This is the 9th year Temasek Polytechnic is organising TPRAWKS, and thousands of students have benefited from being able to make a more informed decision as to their choice of post-secondary education after attending it.

      At TPRAWKS, your child will get to:


      It's a learning journey like no other and we look forward to offering your child the full TP experience. TPRAWKS is free, but places are limited, so do encourage them to register and secure their place before their exams!

      Register online now at

      Warm regards,
      The TPRAWKS Team
