The NMSBVI Orientation & Mobility (O&M) Inventory was developed as a means of quantifying student progress across the many domains that make up O&M. The goal was to create a user friendly assessment tool that quickly allowed an O&M to identify areas of need for individual students, document progress/regression, and make the writing of evaluations, goals, PLEPs (Present Level of Educational Performance), and progress notes quick and painless. Further, there was a need to structure it in such a way as to allow paperwork averse O&Ms to easily track student progress over time. The Inventory aspires to meet these needs.

O&M Inventory Tips

The Inventory is free.
Users don’t need to worry about using a credit card or purchase order and can instead simply download the form from the NMSBVI website.

The Inventory is an Excel workbook.
Users don’t need to know much of anything about Excel. Users do need to have access to Excel to get the Inventory to open. The Inventory will open in Numbers as well for those who don’t use PCs.

Save a copy of the Inventory. Then save another copy of the Inventory somewhere else, like a flash drive.
This allows users to access a fresh copy of the Inventory even when Internet access is not available.

It is recommended that users download the Inventory, select ‘file’, then select ‘save as’ and enter something along the lines of StudentNameO&MInventory for each student.
The downloaded form itself never has had data entered into it; it remains pristine and allows users to make as many copies as needed without ever resorting to deleting information entered for another student. Should data be saved on the downloaded form, all that needs to be done is to download the form again.

O&M Inventory Ratings Information

The Inventory derives percentages based on ratings provided by users The ratings are as follows:

0 = The student is not capable of demonstrating the skill or has no need for the skill. For example, a totally blind student can’t use a magnifier to explore an over the counter map. A student with 20/70 acuity and a stable condition, such as albinism, won’t need to learn 3 point touch as s/he can simply see when a sidewalk is present.

1 = The student doesn’t not yet demonstrate the skill but may or will learn the skill. For example, a 6 year old isn’t going to discuss the positive and negative aspects of clockwise and counterclockwise street crossings. The same student, when older might master that skill.

2 = The student only demonstrates the skill with verbal and/or physical prompting. For example, a student may only move the cane in a protective arc when someone keeps prodding.

3 = The student sometimes demonstrates the skill without verbal and/or physical prompting. For example, the student may stop walking when the sidewalk ends on occasion but often requires a prompt to stop and locate the sidewalk needed to complete the route.

4 = The student demonstrates the skill and verbal and/or physical prompting are rarely needed. For example, the student may identify parallel traffic in the near lane almost all of the time but every now and then confuses it with parallel traffic in the far lane.

5 = The student demonstrates the skill consistently and without verbal and/or physical prompting. For example, once the student has figured out one cardinal direction the student can always deduce the remaining three.

O&M Inventory Information

It is easy for users to navigate between pages of the Excel workbook. Along the bottom edge of the screen are a number of tabs with names that correspond to the 15 domains covered in the Inventory. Clicking on a tab takes the user to that page. Alternately, the user can use keyboard commands Control + Page Up and Control + Page Down to move between the tabs as well.

The Front Page includes the 15 domains covered in the Inventory (3A-17A), blue and yellow (which are NMSBVI’s school colors) shaded areas, an area (1A) to insert the student’s name, and areas to insert the date (1b-1m) the Inventory is completed. Each blue and yellow column represents one assessment period. There are 12 total blue and yellow columns which could be used to track progress on one student over 12 assessment periods. Those assessment periods could be quarterly, yearly, or more widely spaced depending on user need. Whatever the time period between assessments, the user will have data in one handy place (the page prints out as one sheet) over multiple assessment periods. There is also a line in which the O&M can set a goal (B19-M19) and a line right below it that calculates the progress to the goal.

The other pages of the Inventory have a different layout from the front page. Most importantly, these are the pages where the user enters data. Once the appropriate page has been located the user can enter the month and year (1D, 1F, 1H, 1J, 1L, 1N) the assessment is being completed. The user then enters data in the column under “Input Data” (columns C, E, G, I, K, M). To the left of the column the user will see the skill that is to be rated. The user rates the student 0-5 (see above scale, which is repeated on each page of the Inventory). It is easiest to click on the first white cell under “Input Data”, enter the appropriate number, arrow down, enter the appropriate number and so on. Each page contains 12 different assessment periods, which go from left to right and from top to bottom—data is entered in 4C (1st assessment) then 4E (2nd assessment) then 4G (3rd assessment) through 4M (6th assessment), then down the page to the next set of six assessment periods. The aggregate data is transferred automatically to the front page.

It takes about 30 minutes to complete the Inventory for a student who has worked on almost all of the assessment areas while reassessment takes 10-15 minutes; user mileage will vary. The Inventory was created with the measurable nature of IEPs in mind. Instead of crafting goals such as:

Student name will improve his crossings as demonstrated by consistently identifying parallel traffic in the near lane by pointing to the parallel traffic in the near lane 80% of trials/8 of ten trials by the end of the 2012 school year.

The user has the option of writing a goal such as:

Student name will improve his O&M skills as demonstrated by increasing his score on the O&M Inventory Street Crossing domain from 69.9% to a minimum of 75% by the end of the x school year.


Student name will improve his O&M skills as demonstrated by increasing his score on the O&M Inventory from 83.3% to a minimum of 88.5% on the O&M Inventory by the end of the x school year.

The Inventory is designed to show progress over time in the domains of O&M instruction, not serve as a letter grade. Also, the Inventory is primarily designed for O&M students who are already in school as well as adults in rehab settings. O&Ms serving very young students are encouraged to use the B-6 O&M Inventory, developed by NMSBVI O&Ms who work with children in that age range.

While testing out the Inventory it was revealed that students with multiple impairments tended to score very poorly and that their scores were not likely to improve dramatically over time. The NMSBVI O&M (M)Inventory was created specifically for students with multiple impairments. The 15 domains have been rethought with these students in mind. The result is a tool that will hopefully provide meaningful evaluation of students with multiple impairments.

The O&M Inventory and (M)Inventory are tools that O&Ms can use to assist in organizing instruction. They are not intended to replace the training and judgment of Certified Orientation & Mobility Specialists. O&Ms will cover topics not found in the Inventory and (M)Inventory and may not cover some topics in the Inventory and (M)Inventory.

As an added bonus, the Inventory – and (M)Inventory – has also proven useful in quickly dispatching other paperwork, such as PLEPs (Present Levels of Educational Performance), IEP goals and progress notes in very short amounts of time. Here are examples of a PLEP and progress note (front page of Inventory truncated due to ‘portrait’ layout of this document) using the Inventory:

The above PLEP and progress note were both quick to do and highly informative to a parent who has been given an explanation as to what the Inventory is and how it works. It allows the parent to identify areas where progress is made and ask questions about areas where little or no progress has been made. Even without the accompanying note it’s possible to view the chart and see that much of the progress in the past quarter came in the domains of Rural Travel and Atypical O&M skills. The importance of explaining what the Inventory is to the parents can’t be overstated. In the example above, a parent might wonder why the student scores in the 40s or below in the domains of Indoor O&M, Self Protection, Guided Travel and Cane Skills. An explanation that the student hasn’t worked on the skills in those domains (presumably due to a plan to include them later) goes a long way in assuring a parent that those scores are not an indication of poor performance on the part of the student.

The 15 domains used in the NMSBVI O&M Inventory were drawn, with some modification, from Hill & Ponder. TAPS was not used as a reference but, as the industry standard for so long, it clearly had an influence on the Inventory. Basic concepts were also drawn from other tools, such as Finding Wheels, via years of experience/exposure to them. Most directly, the author of the Inventory wishes to thank Dona Sauerburger for her invaluable input on the street crossing section of the Inventory. Her excellent website ( is a tremendous resource for O&Ms. Other O&Ms have contributed to the Inventory over the years via suggestions to add or remove skills or areas. Because the Inventory is a computer based tool it can and has changed due to user input. Feedback is highly encouraged.
