This study aimed to integrate Jeffreys Amazing Statistics Program in teaching Statistics and Probability to improve the engagement and achievement of students. This study utilized the pre-experimental method of research design. The respondents were 120 ACTS Computer College Grade 11 Senior High students. Two instruments were used in this research: the test questionnaires which served as the formative and summative tests and a survey questionnaire in the form of checklist which was used to evaluate the use of software in teaching Statistics and Probability and its relation to the students engagement and achievement. The results revealed that students had very high acceptability regarding the integration of JASP in terms of accessibility, functionality and perceived enjoyment. Efficiency was the only aspect of JASP integration on which the students have had high acceptability. Students were always engaged cognitively in class because of JASP.  Students were often behavioural and emotional engaged in class with the help of JAPS. The integration of JASP further shows that there was an improvement in the academic performance of the students as disclose by overall average score in the result of the summative test which is remarkably higher than formative test. Data revealed that there are significant differences between students test results on formative and summative assessments of their learning. Integration of Jeffreys Amazing Statistics Program has significant correlation on the Students Engagement and Achievement. Based from the result of the study the researcher recommended that varieties of applications should be used by teachers to teach mathematics and students must use different software in solving word problems in order to achieve more interactive, innovative, and efficient instructional materials that will enhance the mastery skills and engagement of the students.
