Welcome to dese.mo.gov. We hope you enjoy the site, and we welcome your feedback.


Here at DESE, we want to extend our thanks to many educators across Missouri who have generously given their time and expertise to help with assessment development projects these past several months. If you are interested in helping with future projects, please contact Kristen McKinney (kristen.mckinney@dese.mo.gov).

As always, please contact me with your questions, ideas and concerns. 

Thank you for all you do for our students of Missouri!

MLS Support Documents

Missouri Learning Standards Science Expectations

The three dimensional learning model found within the Missouri Learning Standards is consistent with the idea found among Next Generation Science Standards (NGSS), Massachusetts(link is external) and South Carolina. Any links or directions to resources are intended to enhance understanding of the three dimensions of learning as well as providing some additional guidance to teachersprincipals and parents.

K-5  |  6-12


The intent of this crosswalk is to enhance understanding of the changes to the science expectations.  This document does not represent the full breadth of change associated with the new expectations. Science and Engineering Practices, as well as Crosscutting Concepts are important components to understanding the changes. Science and Engineering Practices are summarized in Appendix F of NGSS; Crosscutting Concepts are summarized in Appendix G of NGSS. Both appendices provide progressions as well.

Science Resources for Teachers

Missouri Department of Conservation – "Discover Nature Schools"

Missouri Department of Conservation coordinated with Missouri educators to develop an engaging, ecology-based curriculum aligned with our new science MLS expectations. The units are free resources that cover pre-k through high school content using inquiry-based methods. Below are flyers for each of the five units as well as crosswalks to the science MLS and NGSS. Teachers may visit the Conservation Department’s teacher portal to learn more about Discover Nature Schools, receive the free materials, and learn about additional grants.

National Association of Biology Teachers (NABT)

  • NABT resource page has links to all things biology including instructional materials, videos, student resources, articles and videos.

Missouri Environmental Education Association (MEEA)

  • MEEA has an excellent array of resources for teachers and districts to utilize. Lessons, assessments, training, links to parks and conservation areas across Missouri.


  • Science Teachers of Missouri provides an array of science resources to benefit teachers and students in classroom, lesson planning and professional development.  

Missouri River Relief

  • Looking for resources for teaching about the Missouri River, examples of river action projects, or ways to take learning outside? You’ve come to the right place. You're just a little early.

Science Friday

  • Science Friday offers free STEM activities, lessons, and resources for parents and educators.     

The Concord Consortium

  • We're a non-profit educational technology laboratory for science, mathematics and engineering. Our pioneering work brings technology's promise into reality for education.

Next Generation Science Standards (NGSS)

  • The teacher resources link provides pages of resources to assist teachers and districts with implementing science expectations.


  • National Science Teachers Association provides resources for classrooms, implementation and professional development.

University of California -  Berkley(link is external)

  • Lesson plans, videos, articles, “resource database”


  • MetEd is a free collection of hundreds of training resources intended for the geoscience community. Whether you're an experienced meteorologist honing existing skills or a student looking for new geoscience topics of interest, we have something for you.

Liberty School District Curriculum and Instruction

  • The staff and leadership at Liberty Public Schools has developed and graciously shared a pool of resources relative to implementation of the science expectations.
