Dear Colleagues we are delighted to welcome you to the British School Jakarta and to be hosting the SEASIMS Conference this year. Our school has had a long association with SIMS and we hope that as a group of schools we are able to share our expertise through this conference. We believe that there is still much we can learn regarding the effective use of SIMS and data to support students and their learning. I hope that you find the next few days challenging and engaging and that you take back to your respective schools ideas to further the improvement of your own use of SIMS to benefit your students and support their learning.
