What low vision & visual efficiency involves
- Using a handheld magnifier for near tasks
- Setting up and using a video magnifier
- Using screen magnification, large print, and contrast settings
- Using a monocular telescope to read the board or signs
- Visual scanning strategies to find items on a page or in a room
- Requesting seating and lighting, and caring for eyewear and tools
Baseline and measurement considerations
- Start with the TVI's functional vision evaluation and learning media assessment to choose tools and tasks.
- Score tool setup, such as turning on the video magnifier and adjusting zoom and contrast, as a task analysis.
- Count opportunities to use the right tool in class, such as each time the board has new information.
- Use accuracy for reading or locating tasks with a tool, such as finding 8 of 10 targets on a map.
- The TVI leads data; classroom teachers record real use, and the student can rate how well the tool worked.
Progress-monitoring methods used in these templates
- Opportunity (trial) recording: Each planned or naturally occurring opportunity is recorded as correct/independent, prompted, or not demonstrated.
- Task-analysis checklist: A routine is broken into ordered steps; each step is recorded as independent, supported, or not completed.
- Work-sample analysis: Scoring completed student work (permanent products) against a defined answer key or checklist.
- Direct observation: An adult observes and records the defined behavior during a specified activity.
- Timed probes: A fixed-length timing (for example, 1 or 2 minutes) used to calculate a per-minute rate.
- Frequency (event) recording: Each occurrence of a clearly defined behavior is tallied during a fixed observation period.
- Rubric scoring: Work or performance is scored against written criteria with defined score levels.
How each measure works
- Opportunity (Trial) Data: Number of opportunities in which the behavior is demonstrated, out of a fixed number.
- Task Analysis: Number of routine steps performed independently.
- Percent Accuracy: Percent of attempted items answered correctly.
- Rate per Minute: Count of correct responses per minute on a timed task.
- Rubric Scoring: Score on a rubric with defined criteria and score levels.
Matching data sheets
Each template links to a blank sheet built for its measure. You can also download these sheets on their own:
- Opportunity tracker: Records each opportunity as independent, prompted, or not demonstrated.
- Task-analysis checklist: Marks each step of a routine as independent, with support, or not completed across sessions.
- Accuracy tracker: Number correct out of number attempted, with percent accuracy and support level.
- Frequency & rate tracker: Counts a defined behavior during a fixed observation period. Calculates rate when time is recorded.
- Rubric tracker: Scores each rubric criterion and totals the score for each sample.
Common mistakes when writing low vision & visual efficiency goals
- Writing "will use vision better" without naming the tool or task.
- Practicing tools only in the TVI's room, so they are not used in class.
- Leaving out the student's own choice of tool; many students prefer one tool for some tasks and another for others.
- Measuring with an eye chart score, which is a medical measure and not an IEP skill.
- Writing a goal about wearing glasses rather than caring for them or asking for the access the student needs.
