In April 23, 1913 a news article states Penns Grove voted down a proposed bond issue of $30,000 for the erection of a new high school because the one-acre site was considered too small for 600 school children.  William A. Summerill, a former member of the board of education lead the fight for the larger site.  The high school had to be erected that year
because the grace period to supply a better school facility expired at the end of the school term.  The school board meeting minutes note that on June 17, 1913, land was purchased from F.G. Sparks for $1,000. It is unknown if this purchase was for the new school or another purpose or if the original site was used. They would lease the firehouse again in 1913 for school room space.  The new school would be built in the spring of 1914.  The board considered a six-room school of lumber, but later chose one of brick.  In May 1913 they approved the lowest bid $16,375 of Walter Titus of Paulsboro.  The new school was dedicated on December 24, 1914 and opened January 4, 1915.  The new school was called Pennsgrove High School and was located directly across from the Harmony Street School.  It had nine classrooms and an auditorium of 250 seats.  In a 1917 letter to the Board of Education, Principal Merritt Jenkins states “the entering class may have 56 from our 8th grade, 30 from the Village School. U.P.N. and 10 or 12 from Oldmans.  This means a net increase of about 75 pupils.  We cannot accommodate this number under our present arrangements.  I suggest that provisions be made for additional recitation rooms in the basement and that a small steam heating plant be put in to heat these rooms.” There is also discussion of overcrowding at Harmony Street School and the need for some classrooms in outside buildings.  A 1918 news article states “along came the powder boom and the new high school was overcrowded the first year.”  In 1930 there were 329 high school students and thirteen teachers, an increase of two teachers over 1929.   The Pennsgrove High School housed students in ninth through twelfth grades until 1935 when the new Regional High School opened on Maple Avenue.  At that time, Penns Grove High School on Broad Street became a grammar school and became known as Broad Street School.  In 1936 there were 371 elementary students enrolled in the school for grades 5-8 and nine teachers.  There was one first grade class, three 6th and 7th grade classes and two 8th grade classes.   The school remained open until the 1980’s when it closed for good.  The school was demolished in 2002.
