THE SOCIETY OF FLAVOR CHEMISTS
Testing Protocol
The following describes how one may earn membership under The Society of Flavor Chemists’ (SFC) guidelines, and compliance with its by-laws shall be upheld through the actions of The Society of Flavor Chemists Membership Committee (SFCMC). Candidates for membership should ensure validity of their candidacy as outlined in the SFC by-laws before submitting an application for membership. The SFC Membership Committee Chair will review the candidate applications to confirm compliance with the requirements stated in the by-laws. The SFC Syllabus acts as a guide for expected knowledge content of a candidate and for development of written and verbal inquiries for the SFCMC interview process.
SFC Candidate for Membership Interview Process
- Candidates for SFC Membership will be asked to complete a written test followed by a verbal interview. Sufficient time will be allowed for both the testing and interview process:
a. Both written responses and verbal interviews are generally administered at an SFC meeting.
b. An hour for written responses followed by an hour for verbal interview is a usual time allowance.
c. Addtional time of approximately 15 minutes hsall be available should the candidate show steady and thorough advancement in the process.
2. A written test consisting of 25-30 free response questions shall be presented to the membership candidate:
a. Short written responses should be communicated in order to display candidate’s knowledge to the membership committee.
b. Aroma chemical identification exercises, via samples of flavoring item solutions, shall be included as part of the 25-30 questions.
c. All questions stem from knowledge content areas stated in the SFC syllabus.
d. If during the verbal interview process, it is determined that an Apprentice candidate has enough qualifications, e.g. time, experience, qualified responses, to be raised to the level of Certified, a recommendation may be made that the candidate be voted straight to Certified.
3. The written response test will be reviewed by members of the SFC Membership Committee (SFCMC):
a. The SFCMC members shall agree with criteria set by the SFC by-laws Article II Sections 1c and 2c and as restated in this document section 4 (below).
b. The written response test shall act as an indicator to the interview team of the expertise and limitations of the candidate.
c. SFCMC members who have a history of mentorship or camaraderie with a candidate shall voluntarily recuse themselves from the candidate’s interview evaluation process.
4. The candidate shall be verbally interviewed by the SFCMC members who have proficiently reviewed the candidate’s application for membership and written responses:
a. Apprentice candidates should exhibit sufficient knowledge of raw materials, compounding techniques, flavor formulations, production processes, flavor applications, and regulations to be able to proceed to an independent mode of creativity.
b. Certified candidates must demonstrate working knowledge of the flavor industry, including raw materials, laboratory practices, production procedures, legal/regulatory considerations, and the economics involved in the creation, production, and utilization of flavors.
5. The SFCMC shall determine if the candidate should be recommended for the level of membership to which the candidate had applied.
a. For the written test:
i. Apprentice candidates shall be allowed no more than 20% incorrect or incomplete responses.
ii. Certified candidates shall be allowed no more than 10% incorrect or incomplete responses.
iii. If the number of incorrect responses exceeds the allowed percentage, the SFCMC reserves the right to not proceed to the verbal interview. Candidates who fail to pass the written exam will be notified by the Membership Chair of the “no pass” result.
b. Candidates recommended for membership shall be presented to the SFC membership for a vote at the first possible business meeting following the candidate’s interview.
c. If the SFCMC recommends a “no pass”, the options shall be privately discussed with the candidate. The candidate’s name shall remain confidential.
i. Should the candidate have already earned Apprentice membership, and is in good standing with the by-laws, they will retain the level of Apprentice until they either time out or upgrade successfully.
6. The SFC by-laws for membership should be consulted for queries regarding sponsorship and years of training needed to be considered for membership. Should additional information be needed, the Membership Chair can be contacted at membership@flavorchemist.org.
Commitment to Society of Flavor Chemists Membership Standards
The syllabus is intended to provide support and guidance to training programs and is the expected knowledge from which the SFCMC draws interview queries.
No attempt has been made to divide the subject matter into Certified and Apprentice SFC membership categories. Apprentice candidates should be prepared to present a solid understanding of aspects of flavor creation, with the presumption that the candidate may not yet have successfully and independently applied the practice. Certified candidates should be prepared to share broad and deep knowledge, demonstrative of successful independent and original flavor creation skills. It is not likely, nor is it expected, that each candidate will know every aspect of flavor creation.
For the sake of objectivity, no single aspect of the membership interview process shall be more significant than the other. However, the verbal questions will reflect a weighting dependent upon the candidate’s personal job experience. The expectation is that candidates sufficiently fulfill the allotted correct or complete answers on the combination of written and verbal inquiries.
The SFCMC is aware that people test differently (written versus verbal) and shall act to ensure each candidate is treated with fairness and equality. The committee’s role is to ensure that the highest standards of protocol are practiced to maintain the professionalism of the organization.
This document is a reiteration and elaboration of article II.2.c of the SFC by-laws, which states that applicants for Certified Membership “must exhibit a working knowledge of the flavor industry, namely, raw materials, laboratory procedures, production processes, legal/regulatory considerations, and the economics involved in the creation, production, and utilization of flavors.”
Reference Information
Since there are no formal courses in Flavor Chemistry, most of a candidate’s knowledge and training comes from work experience, trial and error, and the counsel of more experienced practitioners of the art. Most candidates for SFC membership will find it useful or necessary to supplement their experience by consulting various published sources of information.
