"Hands down amazing training! Highly effective in application aspects and in the ability of the participants to retain the materials."
- John, Out-of-School Time teacher​

​Each workshop or series is based upon a hierarchy of learning and is available either as a Recording (access anytime)  or Live (scheduled dates):
​
·        Introductory – required baseline of knowledge to be an effective OST professional which should be completed soon after a staff person begins working in a Cambridge OST program
·        Intermediate - explores subject area at a greater depth, plus adds a brief experiential component, e.g., project, presentation; and
·        Advanced – explores deeper complexity of subject and its intersectionality with other subject areas, plus adds a project with practical application to work and manager engagement.

AFCOST offers state-of-the-art training and learning experiences to all of Cambridge’s out-of-school-time (OST) professionals. All workshop content is based upon evidence- and research-based theories pertaining to the holistic development of young people in grades K-12. Workshop content reflects AFCOST’s commitment to support our OST professionals in creating and sustaining culturally-responsive environments where all young people---regardless of race, ethnicity, gender-identity and/or socio-economic status---can thrive in learning, discovering their inherent self-worth, and shaping strong and empowering relationships.  Our training is designed to actively engage participants in the learning process and in applying the training content to their OST work, professional development, and personal well-being. ​

Cambridge Agenda for Children Out-of-School Time has many years of experience in creating vibrant professional development opportunities for OST providers. We offer a wide variety of competency-based training. Participants are provided with active and engaging learning experiences to deepen their competencies in youth development work.  

• Training opportunities are free and open to anyone working with Cambridge youth in OST. 
• Certificates are available for all of our training
• We believe training is most effective when attended by a staff team of two or more, as well as the program leadership when possible.
• All new staff should attend introductory trainings to gain a shared understanding of practices associated with each topic.
