Being the best that we can be...: TKIS Grade 12 Students Top The State again in 2012: 100% of our OP eligible Year 12 students obtained an OP15 or better in 2012, which statistically represents the equal best performance of any school in the state. This is the third year since 2006 that TKIS has achieved this 100% of students achieving an OP15 or better benchmark and we would like to congratulate our students and their teachers for their tireless effort and their amazing passion and commitment.
