Since neither Congress nor the White House will allow federal funding for such research (because of the motherfucking NRA, what else), the Washington Post went ahead and tallied school shootings over almost the past 20 years.
And you wonder why President Trump wants to jail and malign journalists.
Historical Examination of United States Intentional Mass School Shootings in the 20th and 21stCenturies
– published April 19, 2018
A study has just been published in the Journal of Child and Family Studies examining the rate of school shootings in the US: Historical Examination of United States Intentional Mass School Shootings in the 20th and 21stCenturies: Implications for Students, Schools, and Society (Katisyannis, Whitford, & Ennis 2018).
Below is some of the data they presented:

Figure 2 shows the increase in mass school shootings and their related deaths from the first one in 1940 to the most current in early 2018. The United States had no mass school shootings that fit our criteria until 1940, when a junior high school principal killed the superintendent, the high school principal, the district business manager, and two teachers, before attempting suicide, because he thought he was going to be fired at the end of the school year (Williams 2017). The United States had no mass school shootings in the 1950’s and 1960’s, but started a steady increase beginning with a school shooting in 1979 orchestrated by a 16-year-old female with mental health issues who began shooting at an elementary school, killing two adults and injuring eight students and one adult (Daly 2014). Since 1979, the number of shootings increased and then decreased, with the 1990’s being a peak period. However, deaths from shootings went from 12 in the 1980’s, to 36 in the 1990’s, 14 in the 2000’s, and a high of 51 in the 2010’s.
They state later in their discussion section, “When evaluating the number of shooting in the 20th and 21st centuries, it is alarming that in the span of less than 18 years, the 21st century has already seen more deaths than the 20th century”
