  • Check the PHR route: one year of professional-level HR experience with a master's degree or higher, two years with a bachelor's degree, or four years with no degree requirement
  • Check the SPHR route: four years with a master's or higher, five years with a bachelor's, or seven years of professional-level HR experience
  • Read HRCI's definition of professional-level experience, which requires independent judgment, some decision-making authority, in-depth work such as data analysis, interaction across levels, and individual accountability
  • Download the free PHR and SPHR Exam Content Outline PDFs from hrci.org and compare the two blueprints side by side
  • Note that HRCI runs random audits on applications, so write your work history to be defensible with documentation
Apply, then baseline yourself against the blueprint

8 this week

  • Submit the HRCI application and pay the 100 dollar application fee plus the 395 dollar (PHR) or 495 dollar (SPHR) exam fee

5

Total rewards

  • Benefits design: health and welfare, retirement plan types, work-life and wellness
  • SPHR candidates: add executive compensation, board compensation, expatriate and foreign national pay, and equity instruments
  • Do the arithmetic questions by hand so that calculation questions do not surprise you on exam day
Workforce planning, talent acquisition and learning
8

11 this week

  • Sourcing channels, selection methods, structured interviewing and validity of selection tools
  • Background checks and the FCRA process, plus I-9 and E-Verify obligations
  • PHR candidates: Learning and Development at 10 percent, including career pathing and training administration
  • SPHR candidates: workforce forecasting through business cycles, restructuring, divestiture and merger integration

  • Practise reading a small dataset and picking the recommendation the outline expects
  • Review the HR Information Management responsibility statements word by word, because the wording tells you the depth expected
Item types and scenario integration
10

12 this week

  • Practise every item type HRCI lists: traditional multiple choice, multiple response, fill in the blank, drag and drop, and multi-item scenarios
  • For multiple-response items, note that the item tells you how many answers are correct, so count before you commit
  • Work scenario sets specifically, since they require integrating facts across functional areas rather than recalling one definition
  • Sort your practice errors by cognitive level: knowledge and comprehension, application and problem solving, or synthesis and evaluation
  • If most errors are at synthesis and evaluation level, stop rereading and start doing more scenario work
Full-length timed rehearsals
11

12 this week

  • PHR candidates: two full 115-item rehearsals in 120 minutes each, matching the real testing time
  • SPHR candidates: two full 140-item rehearsals in 150 minutes each
  • Take no breaks during the rehearsal, because HRCI schedules none and any break you take eats testing time
  • Score by functional area and weight your remaining revision by the published percentages, not by how uncomfortable a topic feels
  • Schedule the actual appointment now if you have not, and confirm your Pearson VUE confirmation email arrives
Final week and logistics
12

8 this week

  • One last pass over the federal law grid, which is the highest-density recall content on both exams
  • OnVUE candidates: run the Pearson VUE system test on the exact machine and network you will use, turn off pop-up blockers and download the testing software in advance
  • Test centre candidates: confirm the address, plan to arrive 15 minutes early, and check that your ID is unexpired and its signature matches
  • Confirm your name on the application matches your ID exactly, including hyphenated surnames
