Purpose: Researchers and scholars have called for greater attention to collaboration among and between educational leaders in districtwide reform. This work underlines the important social aspect of such collaboration and further investigates the type of professional interaction among/between district and school leaders particularly around the Common Core State Standards (CCSS) and characterizes such interaction by key factors. Research Method: The work takes place in one school district of more than 30 schools serving students from traditionally marginalized backgrounds. Descriptive statistics, multilevel social network modeling, and network sociograms are used to understand the characteristics of professional interactions around CCSS implementation among district and site leaders. Findings: The findings indicate similarities and differences in characteristics of leaders who likely seek CCSS advice and leaders who likely provide that CCSS advice. Leader self-efficacy in implementing the CCSS positively explains the likelihood of both seeking and providing advice behaviors, and yet other factors (organizational learning, leadership, job satisfaction, and CCSS beliefs) each makes different contributions to the likelihood of seeking and/or providing the CCSS advice. Conclusion and Implications: This work suggests a discrepancy of leaders' perceptions between advice seekers and providers, signaling a need for closing the perception gap between advice seekers and providers such that the leadership team could better craft coherent norms of collaboration in instructional improvement. Understanding the "why" of CCSS advice ties may help guide leaders toward the "how" to align professional and social aspects of change.
