Evaluation Rubrics

Twig Science scores highly on NGSS-based rubrics such as NextGen TIME Paper screen evaluation. See below for materials that show exactly how we meet these criteria:


Student Work

Student Progress

Teacher Support


Student Progress Analyze Evidence

Developed in partnership with Stanford University’s SCALE team, the Twig Science 3-D assessment framework supports teachers to evaluate student attainment of the NGSS’s three dimensions and Performance Expectations using a variety of measures. The rubric here explains our assessment framework with details of where you can find evidence of our assessments across the program. The short video provides a visual tour. Module-specific rubrics are below.


All the assessments in Twig Science have been carefully designed to be multi-dimensional.


Students use the three dimensions to make sense of phenomena and solve problems. They articulate their reasoning and explanations through written and drawn explanations, discussions, and presentations.


Of particular note are the Summative Performance Tasks, which are present in all modules and wrap up instructional blocks, requiring students to demonstrate their ability to meet specific PEs. For example, in Grade 1 Module 1 (DQ3L6 Investigate TE p. 114), students meet the PEs 1-LS1-1, K–2-ETS1-2, and K–2-ETS1-3. They do this by comparing different seeds, gathering information of how seeds disperse, and solving the engineering design problem by designing, building, and testing their own a seed model that can be dispersed by the wind.


Every Module in Grades 3–6 also contains Benchmark Assessments, developed in partnership with the Stanford Center for Assessment, Learning, and Equity. Students are challenged to apply the skills and knowledge acquired in the module to new contexts.

Pre-Explorations (Diagnostic Pre-Assessments)


These pre-assessments include multiple choice and constructed responses (both written and drawn). For example, in Grade 3 Module 1 (DQ2L1 Reflect TE p. 119 / DQ2L1 Reflect TB p. 39).

Grade 3 Module 1 DQ2L1 Reflect TB p. 39

All modules contain diagnostic pre-assessments called Pre-Explorations at strategic points in the module that assess prior knowledge and enable teachers to identify misconceptions. Notes in the Teacher Edition and the Progress Tracker support teachers to track students' mastery of their misconceptions and the three dimensions throughout the module. Guidance is also given for how to tailor instruction for students whose misconceptions persist. For example, in Grade 4 Module 4, students complete a Pre-Exploration in DQ1L1 Reflect TB p. 19 and DQ3L1 Reflect TE p. 103.


A version of the Twig Book with sample answers is provided to support teachers to know what success looks like. A redux of this is also included at point of use in the Teacher Editions.
