Campbell-Hallam™ Team Development Survey (TDS™) - Online Edition

A Research-Based System for Team Insight, Alignment, and Action

The Campbell-Hallam™ Team Development Survey (TDS™) is a scientifically grounded, online team assessment designed to help intact work teams understand how effectively they function and where targeted improvements will have the greatest impact. Developed by David P. Campbell, PhD, and Glenn Hallam, PhD, the TDS has been used successfully across corporate, government, healthcare, education, and nonprofit settings for over three decades. It provides teams with standardized, norm-referenced feedback across the most critical dimensions of team effectiveness, supporting self-management, accountability, and continuous improvement

The TDS Online is completed by all team members and a set of knowledgeable observers (e.g., leaders, customers, internal partners). This dual-perspective design allows teams to compare internal perceptions with external reality—an essential ingredient for credible development conversations. Norm-referenced results are reported as T-scores (mean = 50, SD = 10), making it easy to identify relative strengths, developmental priorities, and patterns of agreement or misalignment within the team. Each administration produces individual participant reports and a consolidated team report suitable for facilitated feedback sessions or structured self-guided action planning

Importantly, the TDS is not just a diagnostic tool—it is a development system. The accompanying Facilitator’s Guide provides structured guidance for presenting results, managing sensitive discussions, and translating data into concrete team actions. When used as intended, the TDS reliably stimulates productive dialogue, increases shared ownership of outcomes, and helps teams create focused, realistic improvement plans aligned with organizational goals
