Develop and use a model to illustrate the hierarchical organization of interacting systems that provide specific functions within multicellular organisms.
Clarification statement: Emphasis is on functions at the organism’s system level such as nutrient uptake, water delivery, immune response, and organism response to stimuli. An example of an interacting system could be an artery depending on the proper function of elastic tissue and smooth muscle to regulate and deliver the proper amount of blood within the circulatory system.
Assessment boundary: Assessment does not include interactions and functions at the molecular or chemical reaction level.

Performance Level Descriptions
Every Regents exam question on HS-LS1-2 is written to match one of the performance level descriptions (PLDs) below.
Level 1: Given a model, identify components that show interactions of two systems within an organism. Aug 2026 · Q30 Aug 2026 · Q2 June 2026 · Q1 June 2026 · Q38 Aug 2025 · Q13 Aug 2025 · Q31 June 2025 · Q6
Level 2: Given a model, describe the organization of at least two systems and the interactions of those systems within an organism. Jan 2026 · Q24 Jan 2026 · Q40 Jan 2026 · Q15 Aug 2025 · Q29 Aug 2025 · Q1
Level 3: Complete a model to illustrate that the hierarchical organization of interacting systems provides specific functions within multicellular organisms.
Level 4: Develop and use a model to illustrate the hierarchical organization of interacting systems that provide specific functions within multicellular organisms.
Level 5: Develop and revise a model based on evidence to illustrate the hierarchical organization of interacting systems that provide specific functions within multicellular organisms.

NGSS Dimensions
Performance expectation HS-LS1-2 was developed using the following elements from the NRC document A Framework for K-12 Science Education:
Science and Engineering Practices
- Developing and Using Models
- Develop and use a model based on evidence to illustrate the relationships between systems or between components of a system.
Disciplinary Core Ideas
- LS1.A: Structure and Function
- Multicellular organisms have a hierarchical structural organization, in which any one system is made up of numerous parts, and is itself a component of the next level.
- (NYSED) Disease is a failure of homeostasis. Organisms have a variety of mechanisms to prevent and combat disease. Technological advances including vaccinations and antibiotics have contributed to the prevention and treatment of disease.
Crosscutting Concepts
- Systems and System Models
- Models (e.g., physical, mathematical, computer models) can be used to simulate systems and interactions - including energy, matter, and information flows – within and between systems at different scales.
