Hi Adrian,
In Moodle 1.9.4 and I believe 1.9.3, you can select the attempt number(s) to delete in the View Reports for x attempts located typically in the upper right portion of the SCORM course information. While viewing this report select the attempt or attempts you want to delete using the checkbox to the left of the users name and then scroll to the bottom and select Delete in the drop-down box.

i'm on 1.9.2 and I've just read the documentation on this "This capability is available in Moodle 1.9.4 onwards " - so it is what i want but I will have to get the upgrade. Meanwhile I have locaed the rows in the sco history table I think I can remove manually so will do that today. Thanks.
