Our Experience and our Roots

IGS has provided Quality Educational Experiences since 1992


"To cast a ray of light and move on, leaving it free to develop...

herein lies the first task of the educator."

-Dr. Maria Montessori

In 1992, the Institute for Guided Studies (IGS) guided the first public school district in South Carolina, USA to implement Montessori education. IGS has continued to prepare teachers and provide services to more than ten public school districts in South Carolina.


The distinct qualities of the various training programs offered by IGS are well known and highly respected throughout the United States and other countries. IGS successfully founded the first and only Montessori Teacher Preparation Program to be recognized by the National Ministry of Education, Croatia.

After 17 years of providing exceptional service to both Public and Private schools and ownership was handed off to Mary Helen Cline.


IGS provides consultants to a large number of private schools in Georgia, North Carolina, South Carolina, Utah, New Jersey,   

Dr. Helen K Billings



Dr. Helen K. Billings, was trained by Dr. Giuliana Sorge, who worked closely with Maria Montessori. Dr. B, a Montessori child herself, described herself as an international educator for peace and champion for the child; to her students and protégés when questioning behavior, the environment, actions or dress, would say, “Oh, honey, is that beautiful?”  Dr. Billings was the catalyst for many of today’s Montessori teacher educators and organizations.  There are connecting threads directly linking IGS, MEPI,  and many of our leaders to Dr. B. and her strong beliefs in inclusion and holistic education.  IGS is proud to be one of the training organizations that continues shining the light she kindled.
