Why Rigor Matters

Students who are exposed to a rigorous curriculum gain the life skills that lead them to success in the classroom, and a lifelong love of learning. In fact, research shows that academic rigor challenges students to think deeper, think in innovative ways and develop a more sophisticated understanding of important ideas. Our students leave Arco Iris fully prepared for college, career, and beyond. 

Students learn best in classroom environments where they have an opportunity to build connections with their teachers and peers. Through personalized guidance and innovative teaching methodologies, Arco Iris teachers empower each student to reach their fullest potential, nurturing not only academic excellence but also cultural understanding. The importance of rigor in schools cannot be overstated. Rigorous academic standards challenge students to delve deeper into subjects, hone critical thinking skills and foster intellectual growth. Integrating rigor into classroom instruction is crucial for equipping students with the skills they need to excel in the 21st century.


Immersive Spanish & Singapore Math


There are many aspects of Arco Iris Spanish Immersion that sets us apart from other schools. Between Singapore Math, Immersive Spanish, and integrated art, these are just a few of our specialties that build the foundation of our Oregon state standards-based curriculum. 


The highly acclaimed mathematics program, Singapore Math, builds confident, resourceful problem solvers who can rely on a depth of knowledge that is not found in other methods. Students become adept and flexible thinkers, a skill that serves them not only in math but across all aspects of life. We use Singapore Math because students who use it outperform every other country in math and science; because of its emphasis on math concepts, and because of its in-depth focus on mastering math skills.


Our highly effective immersion model ensures that students not only gain proficiency in the Spanish language, but also develop agility in biliteracy. By immersing students in a rich linguistic environment, we facilitate their journey towards becoming culturally competent across all facets of life. Our young learners embrace diversity and respect the differences in everyone. The Immersive Spanish language curriculum at Arco Iris is one of a kind. Here at Arco Iris, we offer an immersive experience unlike any other - employing a balanced whole-child approach, engaging our students in language acquisition.
