Summary View help for Summary
The Principal and School Climate project was a National Institute of Justice (NIJ) funded study in participating schools across the state of Oklahoma investigating the efficacy of Safe and Civil School Leadership (SCSL) with an additional program called START on Time (START). START was a training program for school principals teaching them skills to foster a safe and positive learning environment for students. This training program consisted of student support as well as resources for principals to use efficacious and data-driven discipline with students. Although first developed over a decade ago, there have been no evidence-based studies investigating the central role principals play within school environments.

Study Purpose View help for Study Purpose
The goal of this study was to evaluate the efficacy of Safe and Civil School Leadership (SCSL) plus START on Time (START) to improve school climate and safety by promoting effective school leadership skills and a unified approach to school-wide hallway management. The specific objectives of the proposed study were (1) to evaluate, utilizing a delayed treatment randomized controlled trial (RCT) design, whether the SCSL plus START program leads to improved leadership skills, school climate, and school safety as evidenced by reduced victimization and bullying/teasing and increased perceptions of safety in comparison to a business as usual (control) condition; and (2) to identify mediators of observed effects on the primary outcome, school safety, based on the researchers' theory of change. These mediators included improved leadership skills, use of data, climate (disciplinary structure and support), aggressive attitudes, and student compliance.
Study Design View help for Study Design
Researchers used a group randomized design. Forty-three principals from schools throughout Oklahoma were randomly assigned to receive Safe and Civil School Leadership (SCSL) plus START on Time (START) or business as usual conditions. Data on primary outcomes and putative mechanisms were collected at baseline and 6 month, 1 year, and 2 year follow-up.

Description of Variables View help for Description of Variables
Variables in the data files collected information related to the prevalence of teasing and bullying, victimization, school climate, disciplinary structure, academic expectations, student support, student perceptions of school safety, aggressive attitudes, and use of data.
Response Rates View help for Response Rates
DS1 (Assistant Principal Data File) and DS2 (Principal Data File) : The valid response rate was 99.3 percent.
DS4 (Student Data File): The valid response rate was 75.5 percent.
DS5 (Teacher Data File): The valid response rate was 81.9 percent.
Presence of Common Scales View help for Presence of Common Scales
Prevalence of Teasing and Bullying. The prevalence of teasing and bullying in a school was measured with a five-item scale.
Victimization index based on Gottfredson's (1999) research
Authoritative School Climate (ASC) Survey
Disciplinary Structure items were derived from the Experience of School Rules scale from the School Crime Supplement to the National Crime Victimization Survey (NCES, 2005).
Academic Expectations
Student Support items were derived from the Willingness to Seek Help scale (Bandyopadhyay, Cornell, and Konold, 2009) and the School Climate Module of the California Healthy Kids Survey (WestEd, 2013).
Student Perceptions of School Safety items were taken from the U.S. Department of Education (2016) School Climate Survey (EDSCLS).
Aggressive Attitudes item were derived from the aggressive attitudes scale (F. L. Huang et al., 2014)

ICPSR also routinely creates ready-to-go data files along with setups in the major statistical software formats as well as standard codebooks to accompany the data. In addition to these procedures, ICPSR performed the following processing steps for this data collection:
- Created variable labels and/or value labels.
- Checked for undocumented or out-of-range codes.
