One Sunday afternoon in April 1981, over a cup of tea, Farrokh Mistree suggested that we start a Sunday School. For stability, Farrokh suggested that the day and venue should always be the same. Hoshang and Arnavaz Sethna offered their home and the day decided was second Sunday of the month. The first Sunday School was held on May 10, 1981 by Farrokh Mistree and has continued since then. After Farrokh left Houston, Vehishta continued with the children with prayer session being conducted by Kety Patel.
With the opening of the Zarathushti Heritage and Cultural Center in 1998, the one room Sunday School has now grown to three sections – Ages 2 to 9 is conducted by Vehistha Kaikobad. Ages 10 to 13 is conducted by Pearline Collector and Zeeba Kayani and Arnavaz Sethna. Ages 14 to 18 is conducted by Sarosh Collector with Behroze Daruwalla and Jenisteen Davier.
