Today is the 16th annual World Teachers' Day as declared by UNESCO. While many countries have their own individual day dedicated to honoring teachers in the country, World Teachers' Day is a day for over 100 countries across the globe to celebrate the profession despite differences. Below are some of the best #WorldTeachersDay tweets that are sure to get you smiling- and remind you of the people across the globe who appreciate what you do.

1. 10.8 Million Primary Teachers Would Be Needed by 2020 for Universal Primary Education

A 2010 study from the Global Campaign for Education found that about 70 million children are annually without primary education. In order to achieve universal primary education, the world needs 10.8 million teachers by that time. For those who are already in the profession- keep on keeping on! 

To achieve universal primary education by 2020 countries will need to recruit a total of 10.9 mln primary teachers #worldteachersday

3. Teachers: In it for the Outcome, Not the Income

With every new school year, teacher shortages and strikes continuously make the news as teachers fight for better pay. The notoriously underpaid profession proves that teachers truly are in it for its importance and the outcome of educating the world's future leaders- not for the income in doing so.

#WhyITeach I thinks it's pretty simple. We're in it for the outcome, not the income. That would make a great T shirt by the way.

5. Education Breaks Cycles

Sometimes we forget about the great importance of education because the tangible results are so far away. But in a remote tribe in India, literacy and the touch of teachers has helped break a crippling cycle of poverty, reminding us of the teacher's power to change and influence.

Without the help of teachers, this remote tribe in India would be stuck in the cycle of poverty. #worldteachersday http://magazine.compassion.com/bringing-a-generation-of-change-to-indias-malto-tribe/
