NFP/FABM Training & Educators

NFP/FABM Educators are listed below according to the method taught to achieve or postpone pregnancy. Most offer classes, both online and in-person that cover the science and biology, how to use the method, the Church’s teaching, and basic charting.

While there are many effective NFP methods and instructors available, the three methods of NFP that the Archdiocese of New York supports include the Cervical Fluid methods, the Sympto-Thermal methods, and the Sympto-Hormonal method listed below, along with the independent organizations who provide training in these methods:

Cervical Fluid Methods

1. The Billings Ovulation Method (BOM) is based on a woman’s daily observations of cervical fluid (also known as cervical mucus). For additional information on the BOM, visit:

For training options available, visit the following sites: by The Marriage Group, LLC by BOMA-USA

2. The Creighton Model FertilityCare System (CrMS) is a comprehensive method for tracking a woman’s fertility by teaching her to understand the cervical fluid or mucus observations throughout her cycle. The Creighton method also serves as a tool for evaluating and monitoring a woman’s reproductive and gynecologic health through the new science of Natural Procreative (NaPro) Technology.

Sympto-Thermal Method

The Sympto-thermal Method (STM) is based on a woman’s observations of her cervical fluid, basal body temperature (waking temperature), and other biological signs (e.g., changes in the cervix). A woman records the characteristics of her cervical fluid secretions and monitors the basal body temperature, which rises after ovulation. Couples cross-check these two primary signs and follow specific guidelines to determine the beginning and end of their fertile days. For additional information on the STM, visit:

Sympto-Hormonal Method

Sympto-hormonal Methods (SHM). Similar to the Sympto-thermal Method, SHMs incorporate cervical fluid observations with a second sign, urinary metabolite hormone levels, to identify days of fertility. The SHM that we endorse is the Marquette Model (MM) which uses a hand-held electronic (ClearBlu Save & Add To Library e Easy) fertility monitor to measure hormones and urinary metabolites.
