Why is it recommended to use different tools and methods for assessing early…

Early literacy is not a single ability but a cluster of interdependent strands — oral language, phonological awareness, print and alphabet knowledge, vocabulary, listening comprehension and emergent writing. Any one instrument samples only a narrow slice of that cluster, and only the behaviour that its own format can elicit. The principle of multiple measures follows from this: the validity of an assessment picture rises as independent sources of evidence about the same construct are added, because each source's blind spot is covered by another.

Applied to a five- or six-year-old, this means no single task can stand for “literacy”. A running record of oral reading shows decoding accuracy but says nothing about vocabulary depth; a rhyme- or sound-matching game shows phonological sensitivity but not comprehension; a drawing with invented spelling shows emergent writing but not listening skill. The method matters as much as the tool: a child who says almost nothing in a one-to-one test may use rich language in dramatic play, and a child who scores low on a worksheet may retell a story in correct sequence. So the teacher varies the tool — checklist, running record, anecdotal record, oral task, work sample, portfolio — and also the method — observation during free play, one-to-one interaction, small-group activity, and evidence collected repeatedly over weeks.

Set against the near-miss aims:

• Assessing one skill in depth needs only one well-chosen instrument; it narrows the evidence base instead of widening it, and leaves the remaining strands unobserved.

• Focusing on group performance yields a cohort average, whereas foundational-literacy decisions in a primary classroom are taken child by child, one learner profile at a time.

• Reducing the teacher's workload is an administrative concern, and gathering evidence through several tools over several weeks in fact adds recording work; ease of administration is never a source of assessment validity.

The recommendation therefore rests on coverage and validity together: different tools and methods are used to capture the diverse aspects of children's learning — the several strands of emergent literacy and the varied situations in which a child actually displays them — which is exactly what one test administered once cannot do. This is the same reasoning that underlies continuous and comprehensive evaluation in the NCF and the assessment guidance of the NIPUN Bharat / Foundational Literacy and Numeracy framework.
