The school, which was founded in 1916  lasted for about 6 decades.
When it was most successful, it had 3 parallel classes through grade 6 and 2 parallel classes for grades 7 & 8 . The loss of a class was partly due to those parents who subsequently sent their sons to (public) Junior High School.
In the mid to late 1960s this was still the situation. The end was relatively rapid, going from approximately 600 students mid 1960s to an estimated 200 students by 1970.

- Mrs. Bella Nemiroff, (unofficial) English Principal
- Rabbi Carlin (principal 196? - 1977)
- Rabbi Akiva Wadler (1978 - final year of the school)
Although when the Yeshiva closed, the area was becoming much more Chasidic, the area included 2 other well known long-time non-Chasidic schools. Down the block from Etz Chaim was a girls school, Shulamith  and, 7 blocks away, another boys school, Toras Emes .
These schools moved to Flatbush, unlike Etz Chaim, which closed.
