# ABLLS-R (Assessment of Basic Language and Learning Skills — Revised) ## Overview The ABLLS-R (Partington, 2006) is a criterion-referenced assessment, curriculum guide, and skills-tracking system for children with autism and other developmental disabilities. It contains 544 skills organized into 25 skill areas, each task-analyzed into component steps. Unlike milestone-based tools, the ABLLS-R provides a fine-grained, task-analyzed breakdown of each skill, making it particularly useful for writing precise instructional programs. ## Structure: 25 Skill Areas ### Basic Learner Skills (Areas A–Q) | Area | Domain | # of Skills | Description | |------|--------|------------|-------------| | **A** | Cooperation and Reinforcer Effectiveness | 15 | Prerequisite compliance and motivation: comes when called, sits in chair, follows basic instructions, works for reinforcement | | **B** | Visual Performance | 27 | Matching, sorting, block patterns, puzzles, sequencing, design copying | | **C** | Receptive Language | 57 | Follows instructions, identifies objects/pictures, identifies by function/feature/class, follows multi-step directions | | **D** | Motor Imitation | 18 | Imitates gross motor, fine motor, and oral motor movements | | **E** | Vocal Imitation (Echoic) | 12 | Imitates sounds, syllables, words, and multi-word phrases | | **F** | Requests (Mands) | 22 | Manding for items, actions, information, using varied sentence structures | | **G** | Labeling (Tacts) | 49 | Labels items, actions, properties, categories, functions, features, emotions | | **H** | Intraverbals | 62 | Fill-ins, WH-questions, describing, reasoning, conversational responses | | **I** | Spontaneous Vocalizations | 10 | Spontaneous labels, comments, descriptions without prompts | | **J** | Syntax and Grammar | 18 | Pronouns, plurals, verb tense, sentence structure, prepositions | | **K** | Play and Leisure | 17 | Independent play, constructive play, imaginative play, game play | | **L** | Social Interaction | 28 | Greetings, sharing, turn-taking, responding to peers, cooperative play | | **M** | Group Instruction | 10 | Attending in group, following group instructions, waiting, raising hand | | **N** | Classroom Routines | 13 | Transitions, following schedules, managing materials, lining up | ### Academic Skills (Areas O–R) | Area | Domain | # of Skills | Description | |------|--------|------------|-------------| | **O** | Generalized Responding | 8 | Demonstrates skills with novel stimuli, people, settings | | **P** | Reading | 25 | Letter identification, sight words, decoding, comprehension | | **Q** | Math | 38 | Rote counting, object counting, number identification, operations, money, time | | **R** | Writing | 16 | Pre-writing strokes, letter formation, name writing, sentence writing | | **S** | Spelling | 15 | Letter-sound correspondence, CVC words, sight word spelling | ### Self-Help Skills (Areas T–Y) | Area | Domain | # of Skills | Description | |------|--------|------------|-------------| | **T** | Dressing | 20 | Removing/putting on each garment, fasteners, shoe-tying, weather-appropriate dressing | | **U** | Eating | 13 | Utensil use, drinking, opening containers, cafeteria routines | | **V** | Grooming | 15 | Hand washing, tooth brushing, hair combing, bathing | | **W** | Toileting | 10 | Toileting routine, initiating, independence, bowel/bladder training | | **X** | Gross Motor | 25 | Walking, running, jumping, climbing, ball skills, balance | | **Y** | Fine Motor | 20 | Grasping, cutting, stringing beads, coloring, manipulating small objects | ## Scoring System Each skill within an area is scored on a task-analyzed continuum. The ABLLS-R uses a grid format where: - **White/empty cells:** Skill not yet present - **Partial fill:** Emerging skill (some components mastered) - **Full fill:** Skill mastered to criterion Individual task items are scored based on specific criteria defined for each task. For example, in Tacts (Area G): - **G1:** Labels 2 items — Score: 0 (none), 1 (labels 1), 2 (labels 2+) - **G4:** Labels 25 items — Score: 0, 1, 2, 3, 4 (with specific count ranges per level) The scoring criteria vary by task — always refer to the ABLLS-R manual for task-specific scoring rubrics. ## Administration ### Methods - **Direct testing:** Structured trials in DTT format or natural environment - **Observation:** Watch during free play, snack, transitions, social interactions - **Caregiver/teacher report:** For skills that occur primarily at home or in specific settings - **Review of existing data:** Prior assessment results, data sheets, progress notes ### Administration Guidelines 1. Begin with Area A (Cooperation) — if cooperation is poor, prioritize it before assessing other areas 2. Assess foundational skills first: Visual Performance (B), Receptive Language (C), Motor Imitation (D), Echoic (E) 3. Move to verbal operants: Mands (F), Tacts (G), Intraverbals (H) 4. Assess academic, social, and self-help areas based on the individual's developmental level 5. Do not attempt to administer all 544 items in one session — spread across multiple sessions 6. Record the date of each scored item for progress monitoring ### Assessment Timeline - **Initial assessment:** 3-8 hours across multiple sessions depending on the individual's repertoire - **Reassessment:** Every 3-6 months, focus on areas being actively taught - **Ongoing tracking:** Update individual task scores as mastery is demonstrated in programming ## Linking Results to Program Development ### The ABLLS-R as a Curriculum Guide The ABLLS-R is designed to double as a curriculum. Each task in the assessment corresponds directly to a teachable skill. The assessment results identify: 1. **Mastered skills:** Foundation for building more complex repertoires 2. **Emerging skills:** Immediate teaching targets — start here 3. **Absent prerequisites:** Must be taught before dependent skills 4. **Skill gaps:** Areas where expected developmental skills are missing ### Program Development Process 1. **Complete the assessment** across all relevant areas 2. **Identify priorities** using this hierarchy: - Cooperation and reinforcement effectiveness (Area A) — address first if deficient - Manding (Area F) — functional communication is always a priority - Skills that reduce barriers to learning - Skills that increase independence - Skills identified in the IEP or treatment plan 3. **Select 5-15 concurrent programs** depending on service intensity 4. **Write teaching procedures** for each program based on the task analysis in the manual 5. **Establish mastery criteria** (e.g., 80% across 2 consecutive sessions, 3 different people) 6. **Track progress** on the ABLLS-R grid at regular intervals ## Tracking Grids and Progress Monitoring The ABLLS-R includes tracking grids that create a visual representation of skill development: - Shade or color-code cells as skills are mastered - Use different colors for different assessment dates to visualize progress - A "staircase" pattern (left-to-right fill) indicates steady acquisition - Flat profiles across an area indicate a plateau requiring instructional modification - Scattered mastery (random cells filled) may indicate rote learning without generalization ## ABLLS-R vs VB-MAPP: When to Use Which | Factor | ABLLS-R | VB-MAPP | |--------|---------|---------| | **Structure** | Task-analyzed (544 items) | Milestone-based (170 milestones) | | **Granularity** | Very fine-grained; individual task steps | Broader milestones with criteria | | **Developmental framework** | Not organized by developmental levels | Three developmental levels (0-48 months) | | **Barriers** | Not assessed | 24 barriers assessed | | **Transition planning** | Not assessed | 18-area transition assessment | | **Curriculum linkage** | Directly doubles as curriculum | Links to curriculum but not as detailed | | **Best for** | Detailed program planning, tracking incremental progress | Overview of developmental level, transition decisions, barrier identification | | **Choose when** | You need precise teaching targets and task analyses | You need a developmental snapshot, barriers analysis, or transition planning | **Clinical recommendation:** Many BCBAs use both — VB-MAPP for initial developmental snapshot and barrier identification, then ABLLS-R for detailed programming and ongoing tracking. ## Common Clinical Patterns | Pattern | Interpretation | Action | |---------|---------------|--------| | Strong Area B (Visual), weak Areas D-E (Imitation) | Visual learner, not yet imitating — common early presentation | Use visual matching strength to build imitation (match-to-sample → motor imitation transfer) | | Area A scores low | Cooperation deficit — reinforcers not established or instructional control absent | STOP other programming; focus on pairing, reinforcer conditioning, compliance training | | Areas F-G strong, Area H weak | Can request and label but cannot respond to verbal stimuli conversationally | Transfer from tact to intraverbal; use fill-in and feature/function prompts | | Self-help areas (T-Y) not assessed | Common oversight in clinic settings | Ensure home-based goals address self-help; collaborate with caregivers for data | | Area O (Generalization) consistently low | Skills are prompt-dependent or context-bound | Build generalization into every teaching program: multiple exemplars, settings, people | ## Key References - Partington, J.
