Perimeter is the distance around a two dimensional shape, a measurement of the distance around something; the length of the boundary. A perimeter is a closed path that encompasses, surrounds, or outlines either a two dimensional shape or a one-dimensional length. The perimeter of a circle or an ellipse is called its circumference.
Test levels 9-14 are administered to students from third grade through twelfth grade. Like test levels 5–8, the primary purpose of levels 9-14 is instructional development. School districts use the standardized achievement battery to learn supplementary information useful in choosing curriculum and lesson planning.
In geometry, the circumference (from Latin circumferens, meaning "carrying around") is the perimeter of a circle or ellipse. The circumference is the arc length of the circle, as if it were opened up and straightened out to a line segment. [1] More generally, the perimeter is the curve length around any closed figure.
A test may be administered formally or informally. An example of an informal test is a reading test administered by a parent to a child. A formal test might be a final examination administered by a teacher in a classroom or an IQ test administered by a psychologist in a clinic. Formal testing often results in a grade or a test score.

The formative assessments aim is to see if the students understand the instruction before doing a summative assessment. [10] (3) Summative assessment – This is generally carried out at the end of a course or project. In an educational setting, summative assessments are typically used to assign students a course grade, and are evaluative.
Formative vs summative assessments. Formative assessment, formative evaluation, formative feedback, or assessment for learning, [1] including diagnostic testing, is a range of formal and informal assessment procedures conducted by teachers during the learning process in order to modify teaching and learning activities to improve student attainment.
A common compactness measure is the isoperimetric quotient, the ratio of the area of the shape to the area of a circle (the most compact shape) having the same perimeter. In the plane, this is equivalent to the Polsby–Popper test.
Peer assessment, or self-assessment, is a process whereby students or their peers grade assignments or tests based on a teacher's benchmarks. [1] The practice is employed to save teachers time and improve students' understanding of course materials as well as improve their metacognitive skills.
