Third Grade English: Getting Started - Beginning-of-Year Diagnostic Assessment

The Beginning-of-Year Diagnostic Assessment provides an opportunity to discover what you already know and identify the skills where you can grow as you enter third grade. This assessment is not a test with a pass or fail grade; rather, it is a personal snapshot of your reading, language, and writing capabilities. Take your time, read every passage and question carefully, and complete each section to the best of your ability.

Understanding the Diagnostic Assessment

A diagnostic assessment acts like a map at the start of a hiking trail. It shows where your journey begins, highlights the strong skills you already have in your backpack, and points out the new trails you are about to explore.

The Silver Whistle

Leo found an old metal whistle half-buried under an oak tree in his backyard.
It was tarnished and dull, but when he washed away the soil, faint carvings
of leaves appeared on its side. Leo blew into it, expecting a shrill blast,
but only a soft, musical chime drifted into the air.

Within moments, two bluebirds fluttered down to the fence post beside him.
They tilted their heads and chirped back with the exact same three-note melody.
Leo blew the whistle again, slower this time. A gray squirrel stopped gathering
acorns, sat up on its hind legs, and chattered softly. Leo smiled, realizing

The Busy Beaver: Nature's Engineer

Beavers are remarkable semiaquatic rodents known for altering their
surroundings more than almost any other animal on Earth. With broad,
flat tails and powerful orange front teeth, beavers construct dams
across streams using branches, mud, and rocks.

These dams block the flow of flowing water, creating quiet, deep ponds.
Inside the pond, beavers build dome-shaped homes called lodges. A lodge
has underwater entrances, which keeps predators like wolves, coyotes, and
bears from getting inside. The pond also benefits many other animals. Ducks,
frogs, turtles, and fish thrive in the still waters created by the beaver's
hard work. Without the beaver's dam, many wetland habitats would simply
disappear during dry summer months.
