    Hello Jaguar Community!

    We are near the end of our first semester of the 18-19 school year, and our students have been working extremely hard to finish on a high note!  Students will be taking final exams December 18(periods 6 and 3) , 19 (periods 5 and 2), and 20th(periods 4 and 1).  All of the days will end at 11:50 a.m.  The exams are longer than our usual class periods and students must prepare accordingly.  Our teachers will help them prepare for the tests and with great study habits, they will succeed!

    We are beginning the winter season of concerts/performances and our winter sports are also underway.  I hope that you get an opportunity to watch a game or a performance at outstanding Ontario!

    The last day of classes before winter break is December 20th. Classes will resume on Monday, January 7, 2019.  

    Thank you for supporting your son/daughter, please do not hesitate to share any ideas that will make Ontario even more outstanding!
