School History

Theiss Elementary opened its doors for instruction in the Fall of 1974. The Theiss family was among the first German settlers in Northwest Harris County, in an area which became known as the Klein Community. There was a strong family tradition of community involvement and leadership. The hard work, dedication, community support, and sense of unity demonstrated by the Theiss family, are qualities that thrive at Theiss Elementary.

School Rating

Theiss Elementary is rated as a Met Standard campus in Klein ISD.

Counseling Program

Students visit the counselor individually, in small groups, and classes for guidance lessons. Activities include academic, personal, career, guidance, and character education. Throughout the school year, lessons on bullying prevention, and drug-free awareness are embedded in classroom instruction.

Parent Involvement

Theiss has one of the finest PTO organizations in the Klein community. Parents are very involved in and work with the school as partners in their child’s education. Students enjoy many activities that promote positive reinforcement based upon academics, citizenship and character. Our PTO provides learning opportunities that involve helping and supporting others within the Klein community.

Core Curriculum

Theiss presents a well balanced literacy program focusing on reading, writing, speaking, listening and vocabulary. Math instruction integrates the state essential knowledge and skills in an engaging and targeted approach, while the science program teaches students to become critical thinkers. In social studies teachers weave the community and world into the everyday lives of students.

Language Arts

In the elementary ELA program, the emphasis is on the development of fundamental reading and writing skills. Reading instruction includes training in phonics, structural analysis, sight word recognition, context clues, vocabulary development, comprehension, study skills, and literary appreciation. Writing instruction teaches students how to use written language appropriately. Instruction includes specific training in grammar, spelling, handwriting, word usage, punctuation, and capitalization, as well as more generalized training in composing written expressions. Skills in speaking and listening are also taught with the instruction for reading and writing.


At the elementary level, students build a foundation of basic understandings for the following: number operation and quantitative reasoning; patterns, relationships, and algebraic thinking; geometry and spatial reasoning; measurement; and probability and statistics.


At the elementary level, students learn science basic skills and how to identify components of the natural world. Students study life, earth, and physical science concepts.

Social Studies

In grades K-12, students build a foundation in history, geography, economics, government, citizenship, culture, science, technology and society, and social studies skills. The content, as appropriate for the grade level or course, enables students to understand the importance of patriotism, function in a free enterprise society, and appreciate the basic democratic values of our state and nation.
