Introduction
Proficiency Testing Australia (PTA) conducted a survey of companies involved in the PTA Waters (Chemical) series of proficiency testing programs.
The aim of this survey was to obtain customer opinion and feedback concerning the PTA Waters (Chemical) series of proficiency testing programs, which has run since 1992. The survey was conducted in April/May 2015 by PTA’s Quality - Business Development Manager, Frances Watton, using the on-line tool - Survey Monkey. Participants were selected from PTA’s current list of Waters (Chemical) proficiency testing program participants. The contact person for each organisation was emailed information concerning the survey and how to participate on 20 April 2015.
Graphical summaries for each of the questions in the survey are presented in the Results section.
Methods
The survey consisted of ten (10) questions, regarding the following subjects:
- Program quality.
- Suitability of samples.
- Frequency of the program.
- Result submission.
- Content of the summary sheets and final report.
- Timeliness of result notification.
- Participation in other PTA programs.
- Need for new programs.
- Recommending the program to others.
- General Comments.
The majority of the response categories were a ranking from Excellent to Poor. The response “N/A” is an abbreviation for “Not Applicable.”
Results
An email inviting participants to complete the survey was sent to a total of 100 organisations (68 Australian and 32 International). Of these, 30 surveys were completed. This represents a 30% response rate.
