SQA Assessment Arrangements Assessment arrangements allow candidates who are disabled and/or who have been identified as having additional support needs appropriate arrangements to access the assessment without compromising its integrity. Introduction to Assessment Arrangements for Schools and Colleges SQA January 2010, revised June 2013 5. Assessment Arrangements 2013 Requests for Assessment Arrangements made for Scotland: 17,263 candidates (11.3% of candidates) Rest of UK: 145,430 candidates (6.9%) Requests made for 61,680 entries (exams) (8.3% of all entries in Scotland) 6.

Computer Reader (TTS) vs. Human Reader TTS offers an independent means to decoding text. TTS provides greater consistency. Human readers can be more flexible (can read anything). Some learners prefer to use TTS. Studies have shown candidates are more likely to check questions with TTS than using a human reader, resulting in higher scores (Dolan et al, 2005) Computer Readers are allowed in ALL exams, including all GCSE, A-level & Functional Skills exams including those testing reading skills since it allows the candidate to independently meet the requirements of the reading standards 8. A 6th year pupil at Denny High in Falkirk was assessed using the Neale Analysis, reading with and without text-to-speech. Reading herself, her comprehension age was 6 years 9 months. With text-to-speech, it was over 13 years. 9. 2002 need for Digital Question Papers with TTS identified 2003-04 research into specification; development of papers 2004-05 evaluation in 6 schools 2005-06 pilot trials #1 - 31 students used digital papers in 105 examinations 2006-07 pilot trials #2 - 80 candidates used 490 digital papers in 200 examinations 2014 Rest of UK PDF papers will be provided by exam boards (not interactive); UKAAF guidance The Scottish Experience: Research, Development and Trial 10.

Resolving issues with use of digital papers & text-to-speech 17. 1. Voice quality Problem Solution many of the students commented that the synthetic voice was of poor quality and was difficult to understand Nisbet, P.D., Aitken, S., Shearer, N.

Scottish Heather voice licenced for use by Scottish Schools (2007). 2. Scottish Stuart voice developed and licenced for Scottish schools (2011). 18. 2. Pronunciation Problem Solution Text to speech doesnt read every word accurately, 1928 would be read as one thousand nine hundred and twenty-eight. Words are mispronounced, in particular names and places, which can affect the smooth reading of longer passages. Words containing an apostrophe are not read correctly. Nisbet, P.D. (2010) SQA Digital Papers 2010 Report. 1. 2011 and 2012 papers (154 papers; 2,044 pages; 235,205 words!) analysed for mispronunciations 2. 308 terms identified. 3. CereProc updated the voices to fix the pronunciation. 4. Or use a TTS tool with a pronunciation editor. 19. 3. Unreadable image text Problem Solution Some text is an image and cannot be read by the computer: 1. SQA desktop publishers now replace image text with text boxes with selectable, readable text. 2.
