The objective of the current research is to identify the level of achievement of the science curriculum for the fifth grade of elementary school for the dimensions of sustainable development from the point of view of its teachers. Public primary schools in Nineveh Governorate for the academic year (2022-2023) and according to the stratified random sample according to the variables of sex and years of service, In order to achieve the aim of the research and answer his questions, the researcher prepared a questionnaire consisting of (14) items in its final form for the environmental dimension, and the researcher adopted the triple Likert scale through the alternatives (large, medium, and few) and also verified the apparent validity of the tool, as well as its psychometric properties (factor validity). ) in the distinction and internal consistency of all its paragraphs and they were all within the acceptable range, As for the stability, it was calculated in two ways, the first is the repetition, and its percentage was (0.82), and the second was internal consistency through the application of Cronbachs alpha equation, and it amounted to (0.89), which are two high levels of stability. He analyzed it statistically by using the weighted mean equation, the t-test for one sample, and the t-test for two independent samples, and he reached the following results: - The science curriculum achieved the environmental dimension of the dimensions of sustainable development by (77%).In light of the results, the researcher came out with a number of conclusions.1- The science curriculum for the fifth grade of primary school has an intermediate role in achieving the three dimensions of sustainable development (environmental, social, and economic).2- The curriculum had a good role in achieving the environmental dimension.3- The male and female teachers' viewpoints converging on the role of the science curriculum in achieving the dimensions of sustainable development.The researcher also made several recommendations to the relevant authorities.1- The Directorate of Preparation and Training held training courses for science teachers on the concepts and dimensions of sustainable development.2- Emphasizing science teachers in adopting the dimensions of sustainable development when teaching the content of textbooks.
