The Performance Diagnostic Checklist-Human Services (PDC-HS) is a structured functional assessment tool adapted for human service settings, including ABA organizations. It assesses four domains that commonly contribute to staff performance problems: task clarification and prompting, equipment and resources, training and knowledge, and consequences. The tool is administered through a structured interview and produces a profile that guides supervisors toward the most appropriate intervention category. It was developed as a human services variant of Austin's original Performance Diagnostic Checklist (PDC) and has empirical support in applied settings.
The PDC-HS is appropriate when a specific staff member has a defined, recurring performance problem that has not responded to informal supervision. Before using the tool, verify that the performance problem is consistent across time and conditions, that temporary factors (acute stress, workload anomaly) have been ruled out, and that the target behavior is clearly observable and measurable. The tool is designed for individual performance analysis, not for organizational-level screening. It is most useful when you have already noticed the gap but are uncertain which intervention pathway is likely to resolve it.
Administration involves a structured interview typically lasting 15-30 minutes. The supervisor answers a series of yes/no or short-response questions about each of the four domains. Some protocols include a parallel supervisee form that captures the employee's perspective on the same questions. The interview can be conducted with the supervisor alone, with the supervisee present, or completed collaboratively. Administering it jointly with the supervisee often surfaces additional information and promotes buy-in for the subsequent intervention, as the staff member can see the assessment is focused on the environment rather than their character.
After administration, review which domains received responses indicating a problem. Each domain maps to a specific intervention category: task clarification problems call for antecedent redesign (job aids, written SOPs, performance prompts); equipment gaps call for resource provision; training deficits call for Behavioral Skills Training; consequence problems call for adjusting reinforcement or punishment contingencies. If multiple domains are implicated, address them in sequence — typically antecedent and resource issues first, then training, then consequences — to avoid implementing complex interventions before foundational conditions are corrected.
A skill deficit means the target behavior is not in the employee's repertoire — they cannot perform correctly even when conditions are optimal. A performance deficit means the skill exists but does not occur reliably because of environmental factors: unclear cues, absent reinforcement, or insufficient prompting. The PDC-HS distinguishes these by assessing the training domain separately from the consequences domain. Intervening with training for a performance deficit wastes time and may increase staff frustration. Intervening with consequence modification for a skill deficit fails to build the underlying competency. Accurate differentiation is the primary practical value of the assessment.
Yes. The PDC-HS is applicable to any direct-service or support staff role whose performance can be operationally defined. In ABA settings, it is equally applicable to RBTs, BCaBAs, school-based staff, case managers, and administrative personnel whose work affects clinical outcomes. The specific behaviors assessed and the domain questions will differ by role, but the four-domain framework applies across positions. When supervising RBTs specifically, the PDC-HS aligns with the BACB's Supervision Training Curriculum Outline, which emphasizes functional assessment of supervisee performance needs.
The PDC-HS is directly consistent with multiple 2022 Ethics Code standards. Standard 4.04 requires that BCBAs use behavior-analytic methods in training and supervision — the PDC-HS applies functional assessment methodology to supervision. Standard 4.07 requires ongoing performance feedback, and the PDC-HS helps ensure feedback is accurately targeted. Standard 2.01 (Providing Effective Treatment) implies that supervisors ensure staff have the conditions needed to implement treatment correctly, which the PDC-HS systematically assesses. Using this tool is one way BCBAs can document that their supervision practice is evidence-based and ethically grounded.
This is a common constraint in large organizations where pay scales, recognition programs, and incentive structures are set by administration rather than direct supervisors. When formal reinforcement mechanisms are limited, focus on the informal consequence landscape you can control: specific and immediate verbal acknowledgment of correct performance, reduced scrutiny when performance is consistent (which functions as negative reinforcement), opportunities for skill development and greater autonomy, and professional recognition in team settings. Document your analysis and, where appropriate, advocate to organizational leadership for structural reinforcement changes supported by the PDC-HS data.
The PDC-HS is an assessment tool, not a routine monitoring instrument. Use it when a defined performance problem emerges, when previous interventions haven't produced improvement, or during comprehensive periodic supervision reviews for staff in performance improvement contexts. After implementing the recommended intervention, evaluate outcome data for 4-6 weeks before reassessing. If performance improves and stabilizes, continued PDC-HS administration is unnecessary. If the problem persists or shifts to a different domain, re-administer to check whether the initial assessment accurately identified the primary function or whether a secondary contributor has now become the controlling variable.
Include the date of administration, the target behavior(s) assessed, the domains where problems were identified, the intervention(s) selected based on results, and the timeline for implementation and review. Retain copies in your supervision file alongside treatment integrity data, session observation notes, and any written feedback provided to the supervisee. If the PDC-HS is used as part of a formal performance improvement process, document the supervisee's acknowledgment of the assessment and the agreed-upon intervention plan. This record demonstrates that your supervision process is systematic, data-based, and consistent with BACB ethical requirements for behavior-analytic supervision.
