Orientation and Mobility Training

Ever wondered what it takes to be an Orientation & Mobility Specialist at Guide Dogs Singapore? To be qualified, our specialists have to be accredited with a Masters degree in Orientation and Mobility (or related field). Before they start teaching clients, they have to undergo a series of blindfolded activities and clock in a certain number of hours in doing so. To establish a greater sense of understanding on the challenges, O&M specialists aim to internalise and empathise by being blindfolded and executing the exercises themselves. This helps them to be more comprehensive when planning for lessons. Here’s a throwback to a crash course our O&M specialists Simone and Cheryl undergo in 2018 with our mentor Lily.
