Below is the LPSP-written (adapted from Barcroft, 2002) for scoring in the written mode.
Lexical Production Scoring Protocol-written (LPSP-written)
| .00 points | .25 points | .50 points | .75 points | 1 point |
| None of word is written; this includes: • nothing is written • the letters present do not meet any “for .25” criteria • first language (L1) word only is written | 1/4 of word is written; this includes: • any 1 letter is correct • 25-49.9% of the letters are present • correct # of syllables | 1/2 of word is written; this includes: • 25-49.9% of letters correct • 50-74.9% of letters present | 3/4 of word is written; this includes: • 50-99.9% of letters correct • 75-100% of letters present | Entire word is written; this includes: • 100% letters correct |
Instructions: (1) “Correct” refers to any letter written and placed in its correct position within a word; “present” refers to any letter written but not placed in its correct position. (2) Accents added or omitted are not considered in determining the presence or correctness of any letter. (3) Determine percentages by dividing letters correct and letters present by the number of letters in the target word. If more letters are written than are in the target word, divide by the larger number. (4) If the same correct letter sequence is written more than once in the same blank on the answer sheet, count the first correct sequence only and do not consider the subsequent correct sequence(s) in any way (i.e., continue scoring as if the subsequent sequence[s] had never been produced at all). (5) If the same target word is written more than once in different blanks on the answer sheet, score it only once in the space where it should be written or, if it is not written in the correct space, score it in the first space where it is written based upon the target word for that space.
