School 21 Diagnostics quickly assess student skill and knowledge gaps, so that teachers can enroll students in Refresher courses if needed. Our Diagnostics utilize adaptive artificial intelligence to efficiently zero on on student capability levels, so most students complete their grade-level diagnostic in less than 30 minutes.
Because School 21's standard courses include review embedded in the grade-level coursework, Diagnostics only identify the areas where student gaps will not be addressed by in-course review.
| Grade 6 Diagnostic |
| Assesses student capability in Operations and Fractions, focusing on critical prerequisite skills from the 4th and 5th grade Common Core State Standards (CCSS). The teacher Diagnostic Report then recommends which students should be enrolled in which refresher courses for the grade (Grade 6 Refresher: Operations, Grade 6 Refresher: Fractions). |
| Grade 7 Diagnostic |
| Assesses student capability in Operations, Fractions, and Algebra Basics, covering critical prerequisite skill areas from the 4th, 5th and 6th grade level CCSS. The teacher Diagnostic Report then recommends which students should be enrolled in which refresher courses for the grade (Grade 7 Refresher: Operations, Grade 7 Refresher: Fractions, Grade 7 Refresher: Algebra Basics). |
| Grade 8 Diagnostic |
| Assesses student capability in Operations, Fractions, and Algebra Basics, covering key skills in the 4th-7th grade levels. The teacher Diagnostic Report then recommends which students should be enrolled in which refresher courses for the grade (Grade 8 Refresher: Operations, Grade 8 Refresher: Fractions, Grade 8 Refresher: Algebra Basics). |
| HS Algebra 1 Diagnostic |
| Assesses student capability in Operations, Fractions, and Algebra Basics, reaching back to skills from the 4th to 8th grade levels. The teacher Diagnostic Report then recommends which students should be enrolled in which refresher courses for the grade (Algebra 1 Refresher: Operations, Algebra 1 Refresher: Fractions, Algebra 1 Refresher: Algebra Basics). |
School 21 provides preparation and remediation courses specifically for the Pennsylvania Keystone Algebra 1 Exam.
