What is required to be eligible for HH?

• A. 1.5 SD
• B. 1.0 SD
• C. 2.0 SD
• D. 0.5 SD

Answer: (A)

The main idea here is that eligibility for a program is often decided by how far a child’s test score falls from the average, using standard deviation units. When a child’s score is about 1.5 standard deviations below the mean, it signals a meaningful deviation from typical performance without being so extreme that only a small minority would qualify. Why this threshold fits best: 1.5 SD below the mean corresponds to roughly the 7th percentile, so it identifies children who are notably behind their peers while avoiding labeling many who are just on the low end of typical variation. This balance helps ensure that those who need the services receive them, but it isn’t overly inclusive. Why the other options don’t fit as well: 0.5 or 1.0 SD below would include too many children who are within expected variation, leading to over-referral. A 2.0 SD below threshold is stricter and could miss children with moderate difficulties who still benefit from eligibility.
