Kindergarten: Letter Knowledge Without Blending
Amara is a kindergartner in the sixth month of school. On the fall screening she scored at the 12th percentile on the Phonological Awareness subtest and the 55th percentile on Phonics and Word Recognition. Her teacher's running record shows 52/52 letter names, 24/26 letter sounds, and 9/10 on first-sound isolation. Syllable blending is accurate, but when asked to blend /s/ /u/ /n/ she repeats the sounds and guesses "sandwich"; asked how many sounds are in "fan," she says two. She recognizes 14 sight words and reads none of the CVC decodable list. The teacher wants to move her into the first-grade decodable set plus a 100-word sight-word program, arguing that "she knows her letters, so she's ready for real reading." The intervention block is 30 minutes, four days a week, and is delivered by a paraprofessional who has been given a scripted program but no coaching this year.
1. Is the teacher's plan to move Amara into first-grade decodable text and a 100-word sight-word program well supported by the data? Justify your answer.

Not supported. Letter-sound knowledge is necessary but not sufficient for decoding. Her first-sound isolation (9/10) and accurate syllable blending show she can access phonemes and larger units; the breakdown is specifically at the phoneme level - blending and segmenting. Decoding a CVC word requires holding three phonemes in sequence and blending them, and her /s/-/u/-/n/ → "sandwich" and "fan" = two sounds show that is not yet available.
If she is placed in decodable text now, she will use pictures and initial letters to guess. That builds a guessing habit instead of orthographic mapping, and 14 sight words is not evidence of readiness.
The two scores are not contradictory - they are a profile. Phonological awareness at the 12th percentile falls below a typical 20th–25th percentile risk cut; phonics at the 55th percentile is a relative strength. The profile says: teach to the constraint (phoneme-level awareness), not around it. Keep the strong letter-sound knowledge warm with brief distributed review, and keep a small amount of sight-word review, but do not make either the core program.
One caution: MAP subscores are screening indicators, not diagnoses. Confirm with a quick in-program blending and segmenting check before finalizing the group.
2. Describe the Tier 2 focus and two specific activities, and explain why the sequence matters.

Focus: phoneme-level blending and segmenting, 15 minutes daily, small group, with letters present for part of the work.
Activity 1 - Continuous-sound blending. Start with two-phoneme words, then three, using stretchable sounds (/s/, /m/, /f/, /n/) before stop sounds. Model "/sss/ /uuu/ /nnn/ - sun," have her echo, then lead. Keep a fixed set of 6–8 words per session so practice trials are high.
Activity 2 - Elkonin boxes with letters. She says the word, pushes a chip per sound, then places the letter that spells each sound. This is the critical step: oral-only phonological work can stall because it never connects to print, while letters plus boxes support orthographic mapping. Immediately follow with reading those same words in a list, then in two decodable sentences.
Sequence rationale: oral blending first (she must hear the phonemes), then letters-added boxes (link sound to grapheme), then connected text (apply). Skipping to text is what the teacher proposed and is the step most likely to fail.
Also embed 3–5 minutes of review on the two missing letter sounds, and make sure the paraprofessional gets modeling and feedback - a script alone does not ensure the correction routine is delivered.
3. What progress-monitoring plan and decision rule would you set, and what would trigger a referral?
Read the worked answer
Measures: a weekly one-minute probe - 10 items blending, 10 items segmenting, and 5 CVC words read. Keep two parallel forms and record the score, not impressions.
Baseline and goal: baseline this week across three sessions. Aim for 8/10 blending, 8/10 segmenting, and 4/5 CVC words within 6–8 weeks. Set an aim line from baseline to goal and plot weekly.
Decision rule: after four consecutive data points, if the trend is flat or rising less than roughly one item per week, change the intervention (more modeling, fewer words per set, more practice trials) rather than waiting out the full cycle. Fidelity matters - observe the paraprofessional twice in the first month.
Referral triggers: if, after 8–10 weeks of well-implemented Tier 2, she is still below the 20th percentile and cannot blend three phonemes, refer for a comprehensive evaluation. Also refer or consult sooner if hearing or speech concerns appear, if letter-sound knowledge begins to erode, or if she shows frustration and avoidance.
Why not wait longer: kindergarten is the window when phonemic awareness responds best to instruction, and a nonresponse pattern after a genuine Tier 2 trial is the strongest evidence a team can have for moving to evaluation.
