Readiness Tier Assignments

Assign differentiated activity tiers using current readiness scores.

Description

Readiness tiers group learners by two ordered score cutoffs.

Readiness tiers group learners by two ordered score cutoffs. The resulting lists describe the current input scores rather than fixed learner ability.^[1]

Assign differentiated activity tiers using current readiness scores.

When to use Readiness Tier Assignments

Use this tool to assign differentiated activity tiers using current readiness scores.

Prepare the lesson timeline, roster, observations or assessment labels requested. Use consistent units and exact identifiers, then choose comparison criteria appropriate to the activity.

How to use Readiness Tier Assignments and understand its results

Prepare the lesson timeline, roster, observations or assessment labels requested. Use consistent units and exact identifiers, then choose comparison criteria appropriate to the activity.
Enter studentIds, readinessScores, intermediateCutoff, advancedCutoff using the field table and calculation rules, then run the tool.
Read foundationIds, intermediateIds, advancedIds. The explanation below defines the units, signs, ordering and any flags or placeholder values.
If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.

Input field	Meaning	Value type; see rules below	Requirement
studentIds	Student ids	list of string	Required
readinessScores	Readiness scores	list of number	Required
intermediateCutoff	Intermediate cutoff	number	Required
advancedCutoff	Advanced cutoff	number	Required

Enter nonempty unique exact learner IDs, aligned finite scores and ordered finite cutoffs. Return three learner lists preserving input order. Equal cutoffs leave no intermediate band.

foundation=score<intermediate; intermediate=intermediate≤score<advanced; advanced=score≥advanced

Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.

Output field	Meaning	Value type
foundationIds	Foundation ids	list of string
intermediateIds	Intermediate ids	list of string
advancedIds	Advanced ids	list of string

Limitations and assumptions

No assessment calibration or activity assignment is performed. Scores and cutoffs can be outside a percentage scale.

Numeric inputs must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Lists are limited to 100,000 entries; the rules above may require smaller limits. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.
