School climate and culture, and its relevance to student achievement has traditionally been a topic of discussion among educators. There have been many research studies dedicated to determining if a school's culture and climate had an effect on student achievement. This study sought to determine if teachers' perceptions of school culture and climate had an impact on student achievement at the elementary and secondary level. In 1963, Halpin and Croft began their research on the organizational climate of schools and suggested that further research be conducted based on their findings. This research sought to determine if there was a relationship between teachers' perceptions of school culture and climate and students' marking period/trimester 1 grades, teachers' perceptions of school culture and climate and students' Start Strong scores, and teachers' perceptions of school culture and climate and school leadership. The New Jersey School Climate Survey was distributed to teachers in four small school districts in Warren County, NJ. Survey data was collected from a total of 62 respondents, and academic data was provided to the researcher on coded spreadsheets. Data analysis was performed using Pearson correlation tests and independent sample t-tests through the use of the SPSS program in order to determine if any potential relationships existed. The data revealed that teachers' perceptions of school culture and climate did not have an impact on student achievement. Additionally, there were a number of relationships that existed with regard to teachers' perceptions of culture and climate and school leadership. The results indicated that the high school respondents answered less favorably compared to the elementary school respondents on the school leadership survey questions. This study may help school leaders have constructive conversations with their staff with regard to the school's culture and climate.
