What We Believe
Male Teacher with Students

We believe that every child has unlimited potential to learn, grow, and thrive.


We believe that when teachers and leaders utilize evidence-based practices that are proven to accelerate learning for all children, that every child can realize his/her full potential.

We believe that by empowering education leaders with key mindsets, knowledge, and skills, they have the ability to achieve educational equity and excellence in their schools.  

We believe that all students have unlimited potential to learn, grow, and thrive. 

Justice, Equity, Diversity,
& Inclusion

We operate with a commitment to justice, equity, diversity, and inclusion, and work continuously to understand how our biases and beliefs influence our choices and behaviors.


We seek to advance educational equity and excellence by designing and implementing equitable systems and structures within and outside our organization. 

Quick Sync
How We Operate


We partner with school districts to design and deliver trainings and coaching that develop systems leaders, school leaders, and teacher leaders.  


We are committed to achieving educational equity and excellence while creating a diverse, inclusive and equitable organization.


We collect evidence that measures the impact of our work, and we systematically analyze and evaluate data to find ways that we can continuously improve.  


Every member of our team has an unyielding focus on embodying the same values and mindsets that are integrated into our work.
