Clarissa began her career with research and impact measurement. From 2009-2011 she managed a Randomized Control Trial for the Massachusetts Institute of Technology's Abdul Latif Jameel Poverty Action Lab (JPAL) on Teach for the Philippines’ predecessor organization, Sa Aklat Sisikat Foundation. It was from the results of this survey that Teach for the Philippines was born. Founded in 2012, Teach for the Philippines focuses its efforts on improving teacher quality and addressing education challenges at the system-level. Through its three core programs, the organization concentrates its resources on recruiting, training, and individually coaching new and existing public school teachers, as well as giving Teach for the Philippines-trained teachers an opportunity to engage in public policy.  Today, oriented towards learning and built on a foundation of research, evidence, and operational excellence, Teach for the Philippines has grown into a nationwide movement that has engaged over 300 young Filipino leaders who are committed to work towards meaningful and positive change. Since its founding, Teach for the Philippines has reached almost 80,000 students and approximately 80% of Teach for the Philippines' alumni continue to work towards education reform, with close to 40% working in the Philippine government, in positions across local government units of placement schools, the Philippine Senate, Office of the Vice President, and Department of Education.  Clarissa is a member of the inaugural class of Obama Foundation Fellows; Asia Society Asia 21 Class of 2016; a 2016 Ten Outstanding Young Men National Awardee; a Fellow of the Philippine Institute of Corporate Directors; and is a delegate of the World Wide Fund for Nature’s Next Generation Council. She holds a Bachelor’s from the College of William and Mary and a Master of Arts in Education, major in Educational Administration from Ateneo de Manila University.
