| IRS990/ProgSrvcAccomActy2Grp/Desc | 0 | The Post Oak School offers an extensive program of parent education. A free series of four classes, repeated throughout the year, offers general information about Montessori education to both prospective parents and interested visitors. The infant-parent program helps parents of toddlers raise happy, self confident children. A variety of other classes, lectures, and other presentations during the school year, some free and open to the public and others by reservation, afford a variety of perspectives on the School's primary purpose of raising intelligent, confident, caring, and self-motivated lifelong learners. |
| IRS990/ProgSrvcAccomActy3Grp/Desc | 0 | Community service is deeply ingrained in the Montessori curriculum, from infancy through adolescence. By the time of Middle School, the entire class spends a half day each week working in small groups at various service agencies around Houston. Elementary students have ongoing relationships with other agencies, whether through regular site visits for volunteer work or by working on projects to benefit needy people in more distant places. Older children routinely learn the benefits and blessing of aiding others in the school's multi-age classrooms. Even the infants, living in a small tight-knit community, discover early on that other people have feelings. |
| IRS990/ProgSrvcAccomActyOtherGrp/Desc | 0 | After an extensive planning and application process, the Houston Montessori Institute had 22 students in the summer of 2021. This training class is taught over a period of three summers and upon completion, the students will be qualified to teach in an Association Montessori Internationale (AMI) classroom. This program has been approved by AMI as well as the Texas Workforce Commission as a Career School. This training center serves the greater Houston and surrounding areas as well as students from around the country and the world. |
| IRS990/ProgSrvcAccomActyOtherGrp/Desc | 1 | Faculty and Staff regularly present at national Montessori conferences and attend both national and international Montessori congresses. The School's administration has led the formation of a national Montessori administrators association. Multiple organizations, whether devoted to Montessori or traditional education, like the North American Montessori Teachers Association (NAMTA) or Independent School Management (ISM) recommend Post Oak materials, policies, and procedures as models of best practices for similar schools. |
