Unpacking Treatment Effect Heterogeneity In A Large-Scale Dropout Prevention Experiment, Thomas Dee, Chloe R. Gibbs, Rebecca Margolit-Chan, Lillian Morrell, James X. Sullivan

Upjohn Institute Working Papers

Timely high school completion is a critical step in successful transitions to post-secondary schooling and the labor market. This randomized controlled trial, deployed in two urban, disadvantaged school districts, tests the effectiveness of a mature and comprehensive student-support program on an unusually large scale (n=2,528). While overall effects on graduation rates are small and statistically insignificant, exploratory analyses reveal notable variation by site and over time, mirroring heterogeneity in treatment timing and program implementation. These findings highlight the challenges of scaling interventions and raise concerns about generalizing results from small-scale, single-site evaluations.

The Expert Myth: Impostor Phenomenon And Research Identity In Counselor Education, Kristi B. Cannon, Kelly Coker, Trent Hepting, Lidian Ramirez-Fiol, Robyn T. Simmons

Journal of Counselor Preparation and Supervision

Imposter Phenomenon (IP) affects counselor educators across career stages, yet it is often conceptualized as an individual deficiency rather than a systemically reinforced experience. This article frames IP in counselor education through the lens of the Expert Myth—a systemic pattern within academic culture that reinforces the expectation that faculty must consistently present as fully knowledgeable, productive, and self-assured to be regarded as credible. We examine how institutional cultures, publish-or-perish pressures, and inadequate mentorship structures create and reinforce imposter feelings, particularly among marginalized faculty and those navigating researcher identity development. Drawing on existing literature, we propose that meaningful intervention requires systemic …
