Evidence
Meta-analysis of studies into formative assessment have indicated significant learning gains where formative assessment is used, across all content areas, knowledge and skill types, and levels of education. Marzano states:
"Recall the finding from Black and Wiliam’s (1998) synthesis of more than 250 studies that formative assessments, as opposed to summative ones, produce the more powerful effect on student learning. In his review of the research, Terrance Crooks (1988) reports that effects sizes for summative assessments are consistently lower than effect sizes for formative assessments. In short, it is formative assessment that has a strong research base supporting its impact on learning." (Marzano, 2006, p. 9).Researchers have concluded that standards-based assessments are an effective way to “prescribe instruction and to ensure that no child is left behind” (Marzano, 2006 p. 13).
The strongest evidence of improved learning gains comes from short-cycle (over seconds or minutes within a single lesson) formative assessment, and medium to long-term assessment where assessment is used to change the teacher's regular classroom practice.

Famous quotes containing the word evidence:
“Washington has seldom seen so numerous, so industrious or so insidious a lobby. There is every evidence that money without limit is being spent to sustain this lobby.... I know that in this I am speaking for the members of the two houses, who would rejoice as much as I would to be released from this unbearable situation.”
—Woodrow Wilson (1856–1924)
“If you are of the opinion that the contemplation of suicide is sufficient evidence of a poetic nature, do not forget that actions speak louder than words.”
—Fran Lebowitz (b. 1951)
“I don’t know what it is about fecundity that so appalls. I suppose it is the teeming evidence that birth and growth, which we value, are ubiquitous and blind, that life itself is so astonishingly cheap, that nature is as careless as it is bountiful, and that with extravagance goes a crushing waste that will one day include our own cheap lives.”
—Annie Dillard (b. 1945)
