ABPath CertLink© (ABPCL) is an online longitudinal assessment designed to support continuous learning and professional development. ABPCL is open to any diplomate of the American Board of Pathology (ABPath). Meeting ABPCL requirements during a 10-year Continuing Certification (CC) Cycle will satisfy the cycle's Assessment requirement for all certifications registered.

Tutorial videos about how to use the CertLink© platform can be found in a playlist on ABPath’s YouTube channel. ABPCL registration, status, and all other aspects of the CC Program can be found in PATHway.

ABPath CertLink Overview

What Is a Longitudinal Assessment?

A longitudinal assessment is designed to assess an individual’s knowledge over time. Answering groups of questions every three months allows the assessment to be continuous, identify knowledge gaps, promote educational opportunities, and allow for remediation.

Using ABPCL to Meet the CC Assessment Requirement

Diplomates should:

  • Design their assessment to best fit their knowledge and practice.
    • A custom assessment can be created from over 30 Practice Areas. The ABPath CertLink® Practice Areas and the topics covered in each can be viewed here.
  • Complete the assigned ABPCL questions each quarter.
  • Use any resources available to them while answering a question other than talking to another person.
  • Read the critique after answering a question.
  • Agree to maintain a fair and secure assessment process.

How Do I Access ABPCL?

Registration for ABPCL can be done through your PATHway account. After you are registered, ABPCL can be accessed by logging in through either the ABPCL homepage or the CertLink® app. 

The ABPCL mobile app is available for download on tablets through the Google Play and Apple App Stores; it has not been approved for use on smartphones. Since the app is approved for tablets only, it will only be displayed and accessible in the app store for tablet devices; participants may not see it as an available app from a smartphone.

How Does ABPCL Work?

  • Between fifteen and twenty-five questions are assigned every three months.
  • Questions may be answered at any time during a quarter. All questions do not have to be completed at the same time.
  • Any resource may be used to answer a question except speaking with another person.
  • Each question has a five-minute time limit and must be answered once started.
  • Immediate feedback is given after answering a question including a critique explaining the question.
  • A second attempt is offered after answering a question incorrectly. ABPath encourages the use of the second attempt after reading the critique provided. This works as part of ABPCL’s built-in feedback and knowledge reinforcement methods. This second attempt is for educational purposes only and does not change the original answer.

For complete information please see the ABPCL Requirements page.

Claiming CME Credits for ABPCL Participation

1.25 SAM-eligible CME credits can be claimed for each quarter of ABPCL participation. The American Society for Clinical Pathology (ASCP) will contact diplomates at the beginning of each year about claiming CME for their previous year’s ABPCL participation. This will start at the beginning of 2020 for the 2019 year. It is not necessary to be a member of ASCP to receive the CME credits.

These credits may be used to meet the Lifelong Learning portion of the CC Program's Reporting requirements.

Can I participate in ABPCL if I do not have to maintain my certifications?

Yes! ABPath encourages diplomates who hold lifetime certifications to answer ABPCL questions. Lifetime diplomates are also able to claim CME credit for their participation.
