A Collective Approach to Increasing Fairness and Reducing Bias on the NPTE

FSBPT uses multiple approaches to ensure the NPTE remains a fair and equitable tool to promote public protection. This article is based on a 2021 webinar presented by Lorin Mueller, Colleen Lettvin, Ashley Ray, Jenny Lapnawan, and Joanne Wagner.

The Federation of State Boards of Physical Therapy is charged with fulfilling its mission to protect the public by ensuring the ongoing excellence, reliability, defensibility, security, and validity of the national physical therapy examination or NPTE.

Passing the NPTE is a critical step in ensuring a candidate has the requisite knowledge to practice safely and effectively. There should be no barrier to any candidate taking the NPTE when considering factors they cannot control, such as race, ethnicity, gender assignment at birth, language, age, disability, or socioeconomic status.

FSBPT's job is to ensure that candidates have an unobstructed opportunity to demonstrate whether they have the knowledge and skill requirements to meet the minimum entry-level requirements to practice physical therapy safely and effectively. To do that, the NPTE and other assessments must contain questions that test only the knowledge of physical therapy practice and avoid US-centric jargon or language that would cause potential differential performance that may favor one candidate over another.

What terms might be unclear? For example, "football" means different things depending on location. Some think of it as a game in which an oval ball is moved forward by running or passing with the hands. Others defined football as a game with a round ball that may not be touched with the hands or arms. Therefore, describing a patient as having been injured playing football might confuse candidates from different parts of the world depending on their expectation

Ensuring fairness is a challenging process, and no one part of the process represents all the various perspectives at play. Accomplishing fairness requires attention throughout all stages of item development.

FSBPT has a rigorous item development process designed to support evidence of content validity at every stage of item development. FSBPT starts by recruiting a diverse group of licensed PTs and PTAs to volunteer to write items and serve on the FSBPT Examination Development Committees and other task forces and committees related to item writing. As a committee, FSBPT volunteers must be representative of the profession in terms of specialty, area of practice, practice setting, geographic location, gender, race and ethnicity, and other pertinent factors.

FSBPT employs a variety of recruitment efforts that include sending notices to specialty groups, advertising at conferences and workshops, and encouraging our existing volunteers, including volunteers who work with minority students, to recommend volunteers.

FSBPT provides formal training to our item writers, item writer coordinators, and committee members on an annual basis on how to ensure that items not only clearly reflect respect and sensitivity to all individuals but also reflect knowledge that is important to physical therapy. Questions must be linked to the NPTE content outlines, have only one unambiguously correct answer, and test knowledge that is relevant to public protection.

Training also includes how to help subject matter experts apply their unique content expertise to item writing and use terms that do not favor one candidate over another. An important aspect of training includes how to reduce construct irrelevant variance by eliminating extraneous or cueing content, for example, content in the question that suggests which answer is correct without requiring the knowledge that is being tested. FSBPT does this in myriad ways, including regularly sharing feedback on items that have been modified for fairness to groups reviewing items.
As part of our ongoing training, FSBPT provides an item writing notebook that includes a checklist of qualifying criteria that reinforces how to minimize bias and maximize fairness across all items. FSBPT checks the items for fairness and for quality at multiple levels of item development. In addition to volunteers and committees, staff physical therapists verify the content of each item, and staff editors evaluate items for style and clarity.

The NPTE Style Manual enforces style conventions, which help provide a consistent testing experience for candidates. This allows them to focus on the content of the questions, rather than distracting or alarming details that might interfere with their thinking process.

For example, the NPTE Style Manual recommends the following:

  • Clinical rather than colloquial terms: "residual limb" not "stump"
  • US customary and metric units for most measures: distance in feet and meters
  • Most abbreviations are spelled out: "ankle-foot orthosis" not "AFO"
    • Acceptable abbreviations are included in the Candidate Handbook
  • Generic terms are used for medications, in most cases followed by a common brand name: lisinopril (Prinivil)
  • Generic terms are used for equipment: "elastic resistance bands" not "Theraband"
  • Patient's age in number of years rather than in generic terms, such as "elderly"

Some of our preferred language is also intended to reduce bias in NPTE questions:

  • Gender-neutral references to patients and therapists
  • "Patient first" language: "A patient who has diabetes" not "a diabetic patient"
  • A patient reports a symptom instead of complains of a symptom
  • A patient adheres to treatment instead of complies with treatment, as compliance implies control and enforcement
  • A patient sustained an injury instead of suffered from an injury, as suffered is an emotional term that implies helplessness

FSBPT also trains volunteers annually on how to use the bias and sensitivity scale, which assesses whether the item avoids language that may foster stereotypical, inappropriate, inflammatory, or derogatory terms towards racial, ethnic, gender, or any age groups. When in doubt, volunteers can flag items to undergo closer review by the Fairness Review Committee.


Bias and Sensitivity Scale
Indicate if the item avoids materials that foster stereotypes, inappropriate terminology, inflammatory material, or a derogatory tone toward racial, ethnic, gender, or any age group
  • Meets Standards
    • Item contains only material & references that are universally familiar to all candidates.
  • Does Not Meet Standards
    • Item contains irrelevant material that may cause differential performance in subgroups of examinees and/or
    • Item contains irrelevant materials that may be viewed as offensive to certain subgroups of examinees
  • Needs Further Review
    • Certain subgroups of examinees may be unfamiliar with construct-irrelevant references however can understand the premise of the question through other cues

 

While FSBPT has many processes in place, it is important to test that these processes are, in fact, working. About twenty staff and volunteers and 300 candidates see an item before it becomes a scored item. Does that mean that someone will catch a problem? To answer this, FSBPT initiated a "secret shopper" experiment.

The Assessment Content Manager selected four item writing volunteers and asked them to intentionally submit problematic items under their names to their item writer coordinators. The experimental items included language that item writers, coordinators, assessment editors, and assessment content analysts were trained to identify and correct.

Only the volunteers and Fairness Review Committee were aware of the experiment. This helped create an environment where the Review Committee could fairly evaluate the quality. All four problematic items were identified and corrected before the items were approved. Based on the experiment's outcomes, FSBPT knew the training was working; problematic items were being caught.

FSBPT also surveys volunteer groups immediately following each meeting to collect information about the item and examination development process to help us internally identify and modify the way that FSBPT provides training and ongoing subject matter expert support.

FSBPT also aims to be fair in other aspects of the exam process. The Candidate Handbook and PEAT are both tools to help students prepare. The handbook offers clear, transparent advice and is freely accessible. PEAT is a practice exam simulating the NPTE and is available at a reasonable cost.

Finally, FSBPT also has external oversight. The Technical Advisory Panel, a group consisting of experts involved in academic or high-stakes examination programs, meets semiannually to provide insight and feedback. The Buros Center for Testing at the University of Nebraska at Lincoln holds FSBPT accountable by ensuring the organization meets accreditation standards. FSBPT collects candidate feedback in the post-administration survey and also seeks feedback from educators.

All of the current systems and checks can instill confidence, but that does not mean there is not more work to do. FSBPT recently engaged an external expert to help refresh the anti-bias tools. FSBPT continues to learn from educators, students, candidates, and other stakeholders and experts as they expand and build upon strategies to ensure fairness on the NPTE.
