21CLHK is where we started as a company so of course we love it – but don’t take our word for it!

Each year when we do a survey more than 95 percent of respondents recommend the conference as “Very Good” or “Excellent” and most stay plan to return if budget and schedule permit.

We hope you register and join our community – below I’ve pased just some of the comments we’ve received from past attendeees over the last 15 years

I have to say, 21CL is by far the conference where I learn the most. Whatever the formula is keep it up! I do enjoy the fact that a lot of the sessions are focused on improving learning and teaching, and not just focused on tech tools – David Lee

Thank you again for the amazing opportunity to be part of the 21CL Conference. The power of the keynote speakers and the energy in the sessions were refreshing, affirming, and impressive. After all the years of Covid and stress, it felt right to gather our thoughts about what matters for education now. – Tatiana Kladova

What made this conference so special was the level of personalization. Unlike conferences that are hosted at large hotels with carpeted conference rooms that look more like casinos than places that inspire creativity, 21CLHK was hosted AT an innovative school. This helped us relate all of the innovative strategies including AI, STEM, PBL, Gamification, etc. to how they might be used in classrooms and with students. As important to the workshops were the connections that stemmed from such a personalized conference. There were social networking hours, small coaching corners, and a conference hotel that had outdoor space that invited synergetic conversations and deeper connections. I will definitely be back again.” – Kyle Wagner

From integrating AI into the classroom to recognising the masks students and teachers wear, 21CL taught participants that innovation can be manifested in many ways. – Sam Vierra

The conference was really very good. Being with, meeting and networking with like-minded educators was very inspiring. The energy and the enthusiasm was infectious.I picked up things in each session that I will use to make adjustments to my teaching. – Katherine Chiu (American International School, Hong Kong)

I know that pulling together a conference like this takes hours of time and a lot of coordination. Thank you for putting on an excellent conference – I look forward to being able to attend another one in the future. – Anonymous

My fourth 21CL and they are getting better all the time. I always leave with new ideas, new friendships, new energy that carries into my planning for the future. It’s my favorite PD event of the year every year! – James Waller (Delia School of Canada, Hong Kong)

Wonderful job! It was very smooth with a lot of different session options. The keynote speakers were inspiring and really gave me a lot to think about. – Tanya LeClair (American International School of Guangzhou, China)

It was great to have our high school students involved in panels and attend the event.  They have lots of ideas to share with teachers, parents and middle school students. They see the same problems I have seen as the Secondary Tech Coach with how some of our teachers are using tech, but I’m hoping it will carry more weight with admin and teachers coming from them. – Nerilee Hall (International Christian School, Hong Kong)

The 21CHK team is phenomenal. I have never attended or presented at a conference that was so well organized and run. You made every presenter feel welcome and supported. Thank you for a fantastic event – Anonymous

This is my first time attending the conference and it has helped me even being more enriched & glad to know that I am part of a bigger community of enthusiastic and very passionate educators 🙂 – Puti Hamid (Sekolah Cikal, Indonesia)

Lovely mix of presenters both big name and teachers with tremendous expertise. Wide range of sessions but with obvious common themes. Well organized and fun. Perfect amount of transition time between sessions. Overall, a perfect mix of inspirational and practical, theoretical and real life, amazing all around. Thank you for organizing, inspiring, and connecting all of us. – Anonymous
