Some time back, the Teller Acuity tests were 'out of print' for a year..
Then, about 2 years ago the University of Washington appointed a new licensee
and we were able to resume shipments. Unfortunately the price had been increased
to almost US $3000. More significantly we began to experience rejections due to
quality problems. These rejections became increasingly frequent and we have now
decided that we will no longer distribute the Teller sets.
In the meantime, the Cardiff
Acuity Set was re-engineered by Cardiff University and provides excellent
results for acuity testing children in the same 6 month to 36 month age range.
The price is less than half the Teller sets at $1200.
